-      These files contain the necessary material for producing
-APL documents with TeX.  It should be pointed out that as written
-in an article published in TUGboat, the system as such can be
-described as a straightforward solution to the problem of making
-nice documents containing APL code.  Instead of trying to achieve
-a completed result, we tell the reader how to use existing MetaFont
-character descriptions as far as possible to provide an APL font
-of reasonably fine quality.  Further development is left to the users. 
-Combined with suitable TeX macros using Digital's mnemonics -- chosen
-because of the popularity of the interpreter among APL users
-(it is really the only one used at our site) -- the font can be used
-smoothly enough.  Furthermore, if combined with an APL workspace
-providing functions for an automatic conversion of APL workspaces
-into TeX code, the system can be used to merge pre-existing
-APL code into documents without the pain of re-writing the code
-in Digital's 2-letter mnemonics. 
-      To produce pixel files from the MetaFont file CMAPL10.MF,
-you have to run MetaFont in your local machine.  By typing METAFONT
-you should get the prompt symbol '*'.  It may be necessary to use
-the form
-
-            METAFONT\INPUT_DIRECTORY = XXXXXX
-
-where XXXXXX is the global name of the directory where the basic
-CMMF definitions can be found.
-The following discussion will then get MetaFont to produce a generic
-font file CMAPL10.360GF:
-
-                 * \relax;
-                 * \mode = imagen;
-                 * \mag = 1.2;
-                 * input cmapl10
-
-Here \mode = imagen was used to get a pixel file for a laserprinter
-with the resolution 200 times 200 pixels per square inch.  It is
-possible that the definition of 'imagen' is different at your local
-site; in the case of error ask the person who installed your local
-MetaFont.  Notice that \mag = 1.2 is needed in case you want to get
-magnified pixels.  The final pixel (because of the resolution 200)
-files will then be named CMAPL10.1800PXL (or whatever you choose
-to call them).  If you want to produce 'small' pixel files for example
-for a screen previewer, use \mag = xxx with an appropriate constant xxx.
-(You can check the form of characters obtained on a teletype terminal
-by using the program GFTYPE.)  Finally, you get a pixel file from
-CMAPL10.xxxGF by running the program GF(TO)PXL.EXE, which should be
-found together with MetaFont.
-        Some people want to use their pixel files on a PC (the
-laserprinter is connected to a PC or for previewing purposes).  In
-that case the pixel files must be downloaded from the host.  We never
-use programs like Kermit for transferring the binary file but
-first convert it to hex form, load the file down as a text file and
-then convert it back.  It is IMPORTANT to notice that pixel files in
-VAXes (say) are composed of 512 byte blocks.  The pixel file itself
-is ended by the pixel_id, which is either 1001 (rasters are in word packed
-form) or 1002 (rasters are in byte packed form).  Many programs running
-on PCs assume that the last 4 bytes of the pixel file really
-represent the pixel_id.  Hence, the pixel files downloaded from the host
-should be CLEANed from garbage (the programs CONVERT and CLEAN are
-given for convenience and to fix the definition of what they should do).
-       MetaFont also produces the file CMAPL10.TFM containing the
-metric information of the characters in the font.  These are needed
-by TeX, and they can be downloaded as such (at least if you are
-using Micro-TeX or PCTeX).
-
-        In order to use the mnemonics, the macros in APLSTYLE are
-needed.  There are basically two ways of merging APL code.  There are
-standard macros called VERBATIM, which enable the user to produce
-'typewriter-like' output.  As APL is modelled on a typewriter style,
-too, it has been reasonable to extend VERBATIM to accept different
-typewriter-like fonts.  The escape sequence \choosett enables you to
-choose the font you want to use.  Thus, \choosett{tentt} swithces
-the standard font CMTT10 on, whereas \choosett{apl} chooses the font
-APL, defined in APLSTYLE by '\font\apl = cmapl10'.  First, you can
-insert APL code into text lines.  In this case you can call any
-APL symbol either by its 2-letter mnemonic (for example \BX produces the
-box symbol) if there is no symbol for it OR otherwise by its name
-surrounded by two @'s.  (The @ character swithces into the current
-typewriter style.)  Thus, @A_B@ produces 'A <-- B' in APL style, because
-'_' is the name of '<--' in Digital's mnemonics.  Secondly, you can
-insert APL code in 'screenlike' mode.  The code is to be delimited
-by the pair \begintt - \endtt.  Example:
-
-\begintt
-    @DL Z_ZNPLUS N;@BXIO    % Here '@' replaces '\' as the escape
-[1]   @BXIO_0               % character
-[2]   Z_N@AB(@ION)@SO.+@ION
-    @DL
-\endtt
-
-Please note that in this case the material between \begintt -- \endtt
-is considered by TeX as a vertical box that cannot be divided between
-pages.  Thus, if you have a long APL function, it might produce
-a message of underfull vbox.

-      These files contain the necessary material for producing
-APL documents with TeX.  It should be pointed out that as written
-in an article published in TUGboat, the system as such can be
-described as a straightforward solution to the problem of making
-nice documents containing APL code.  Instead of trying to achieve
-a completed result, we tell the reader how to use existing MetaFont
-character descriptions as far as possible to provide an APL font
-of reasonably fine quality.  Further development is left to the users. 
-Combined with suitable TeX macros using Digital's mnemonics -- chosen
-because of the popularity of the interpreter among APL users
-(it is really the only one used at our site) -- the font can be used
-smoothly enough.  Furthermore, if combined with an APL workspace
-providing functions for an automatic conversion of APL workspaces
-into TeX code, the system can be used to merge pre-existing
-APL code into documents without the pain of re-writing the code
-in Digital's 2-letter mnemonics. 
-      To produce pixel files from the MetaFont file CMAPL10.MF,
-you have to run MetaFont in your local machine.  By typing METAFONT
-you should get the prompt symbol '*'.  It may be necessary to use
-the form
-
-            METAFONT\INPUT_DIRECTORY = XXXXXX
-
-where XXXXXX is the global name of the directory where the basic
-CMMF definitions can be found.
-The following discussion will then get MetaFont to produce a generic
-font file CMAPL10.360GF:
-
-                 * \relax;
-                 * \mode = imagen;
-                 * \mag = 1.2;
-                 * input cmapl10
-
-Here \mode = imagen was used to get a pixel file for a laserprinter
-with the resolution 200 times 200 pixels per square inch.  It is
-possible that the definition of 'imagen' is different at your local
-site; in the case of error ask the person who installed your local
-MetaFont.  Notice that \mag = 1.2 is needed in case you want to get
-magnified pixels.  The final pixel (because of the resolution 200)
-files will then be named CMAPL10.1800PXL (or whatever you choose
-to call them).  If you want to produce 'small' pixel files for example
-for a screen previewer, use \mag = xxx with an appropriate constant xxx.
-(You can check the form of characters obtained on a teletype terminal
-by using the program GFTYPE.)  Finally, you get a pixel file from
-CMAPL10.xxxGF by running the program GF(TO)PXL.EXE, which should be
-found together with MetaFont.
-        Some people want to use their pixel files on a PC (the
-laserprinter is connected to a PC or for previewing purposes).  In
-that case the pixel files must be downloaded from the host.  We never
-use programs like Kermit for transferring the binary file but
-first convert it to hex form, load the file down as a text file and
-then convert it back.  It is IMPORTANT to notice that pixel files in
-VAXes (say) are composed of 512 byte blocks.  The pixel file itself
-is ended by the pixel_id, which is either 1001 (rasters are in word packed
-form) or 1002 (rasters are in byte packed form).  Some programs running
-on PCs assume that the last 4 bytes of the pixel file really
-represent the pixel_id.  Hence, the pixel files downloaded from the host
-should be CLEANed from garbage (the programs CONVERT and CLEAN are
-given for convenience and to fix the definition of what they should do).
-       MetaFont also produces the file CMAPL10.TFM containing the
-metric information of the characters in the font.  These are needed
-by TeX, and they can be downloaded as such (at least if you are
-using Micro-TeX or PCTeX).
-
-        In order to use the mnemonics, the macros in APLSTYLE are
-needed.  There are basically two ways of merging APL code.  There are
-standard macros called VERBATIM, which enable the user to produce
-'typewriter-like' output.  As APL is modelled on a typewriter style,
-too, it has been reasonable to extend VERBATIM to accept different
-typewriter-like fonts.  The escape sequence \choosett enables you to
-choose the font you want to use.  Thus, \choosett{tentt} swithces
-the standard font CMTT10 on, whereas \choosett{apl} chooses the font
-APL, defined in APLSTYLE by '\font\apl = cmapl10'.  First, you can
-insert APL code into text lines.  In this case you can call any
-APL symbol either by its 2-letter mnemonic (for example \BX produces the
-box symbol) if there is no symbol for it OR otherwise by its name
-surrounded by two @'s.  (The @ character swithces into the current
-typewriter style.)  Thus, @A_B@ produces 'A <-- B' in APL style, because
-'_' is the name of '<--' in Digital's mnemonics.  Secondly, you can
-insert APL code in 'screenlike' mode.  The code is to be delimited
-by the pair \begintt - \endtt.  Example:
-
-\begintt
-    @DL Z_ZNPLUS N;@BXIO    % Here '@' replaces '\' as the escape
-[1]   @BXIO_0               % character
-[2]   Z_N@AB(@ION)@SO.+@ION
-    @DL
-\endtt
-
-Please note that in this case the material between \begintt -- \endtt
-is considered by TeX as a vertical box that cannot be divided between
-pages.  Thus, if you have a long APL function, it might produce
-a message of underfull vbox.

-\section{Introduction}
-This note describes an interesting exercise in using
-\METAFONT\ to produce new typefaces by combining letters
-from standard fonts. As we know, the \APL\ language [6] of
-Kenneth Iverson has never gained the popularity it deserves
-which is largely due to its strange symbol set. Indeed,
-true \APL\ users require a special keyboard to support
-the nonstandard but powerful operator symbols. Moreover,
-putting \APL\ into print has always been a problem, and
-modern low cost computerized typesetting programs do
-not usually support \APL\ style. \TeX\ can be used to
-produce high quality printouts for technical text,
-and it would be desirable to have a possibility to
-mix in \APL\ code. The companion program of
-\TeX ---\METAFONT ---provides a full means for a simple generation
-of an \APL\ font for \TeX, and the purpose of this
-note is to inform other people about the result we
-have obtained at the University of Helsinki. Let us note
-that there are at least three other \APL\ fonts available
-for small computer environments. Indeed, the newsletter
-\APL\ {\it Quote Quad\/}\footnote{*}{{\ninepoint Newsletter of SIGAPL,
-the Special Interest Group for \APL. {\it Quote Quad\/} has the same
-status in the world of \APL\ as TUGboat in \TeX{nical} world.}}
-is produced by using TROFF, and there
-exists a Postscript \APL\ font for the Apple Laserwriter [5] and
-another font for the TEXT typesetting system [2].
-
-Consider the following usual kind of function definition in \APL:
-\choosett{apl}
-\begintt
-        @DLS_SUMSQ N;I
-  [1]   S_I_0
-  [2]   @GO(N<I_I+1)/0
-  [3]   S_S+I*2
-  [4]   @GO2
-  [5]   @DL
-\endtt
-\choosett{sltt}%       %@@@@
-How to write in this code, providing that we have a suitable
-font? The \APL\ font should represent the screen
-output style of \APL\ code and obey the same laws of spacing.
-Hence, it should be a typewriter-like typeface with fixed
-spacing; the same approach for representing \TeX\ input was
-adopted by Knuth in the {\TeX}book.
-The {\it verbatim\/} macros have often been used for importing
-screen or paper outputs into \TeX\ documents; some people
-misuse them for an easy construction of tables etc. In
-{\sltt verbatim}, the typewriter mode is entered by the control
-sequence @\begintt@---that mode is ended by
-@\endtt@. In the same vein, we could enter
-the \APL\ mode by the control sequence @\beginapl@,
-and to end it by @\endapl@. However, it is more convenient to
-augment {\sltt verbatim\/} with {\sltt aplstyle\/} so that
-it can be used with several different typewriter-like fonts.
-(The {\it verbatim\/} macros can be found in the {\TeX}book,
-p.\ 421.)  Since {\sltt\char'100\/}
-(the {\it at sign}) is used as the escape character inside {\it verbatim\/}
-mode, our \TeX\ code might (and in fact does) look as follows:
-\def\endsym{\char'134{endtt}}   % just for using \endtt after \begintt
-                                % without actually ending anything

-The control sequences @\DL@ and @\GO@ are not chosen arbitrarily
-but follow the conventions used in Digital's VAX \APL\ interpreter [1].
-As terminals usually do not support the \APL\ character set, an
-alternative representation by two-letter mnemonics is provided by the
-interpreter. For the most part we have adopted these mnemonics also for our
-\APL\ font. Hence, as an additional bonus the user should find it
-easy to combine his or her \APL\ code with normal \TeX\ code. Thus,
-it is not necessary for a VAX \APL\ user to retype the definitions
-of \APL\ functions in order to be able to use them in documents.
-He or she only has to replace every {\it period\/} used as an
-escape character in Digital's interpreter, by {\sltt\char'100}.
-(There is another syntactical difference between Digital's interpreter
-and \TeX's {\it verbatim\/} mode: for the interpreter
-the third ordinary character after an escape character
-does no longer belong to the escape sequence while \TeX\ admits
-arbitrarily long control sequences.  We take care of this
-by changing certain {\it catcodes\/} temporarily.)

-\section{The \APL\ font table}
-\APL\ symbols are divided into two classes: the primitive symbols
-and those obtained by overstriking two primitive ones. The overstrikes
-are traditionally obtained by typing the first symbol, by using
-backspace to go back one space and then typing the second symbol
-{\sl over\/} the first one. However, in modern \APL\ keyboards these
-double symbols are assigned to non-alphanumeric keys (for example,
-to keys under the {\sltt ALT\/} key). We decided to include only the
-primitive \APL\ symbols in the font table; this enabled us to include
-also the lower-case letters, following modern conventions. (The original
-\APL\ letters were restricted to capitals.) The comment symbol
-@"@ is the only exception since it is keyed in as a double quote.
-Our font is a fixed size typeface with strongly slanted letters.
-Moreover, we have followed the style of best books in \APL:
-all symbols should be drawn with a thin pen to get a touch of
-a typewriter. (This point is clearly witnessed, for example, in [5].)
-The places of some symbols are determined by the \TeX\ font tables.
-For example, the hash sign {\sltt\char'043\/} is used for the
-multiplication sign in VAX \APL, and hence the corresponding symbol
-has the the same octal code (043) as the hash sign in \TeX.
-The font table has the following form:          %@@@@

-\section{The necessary \METAFONT\ files}
-The whole process started when the first author had a paper
-containing \APL\ symbols and was disappointed with the
-quality of the symbols available on the typewriter. Moreover,
-the secretary who had typed the text had forgot a couple
-of lines in the middle of the paper, and the correction of
-such mistakes seemed to be very clumsy in comparison with
-modern typesetting. Then he decided (together with the second
-author) to remedy the situation by creating an \APL\ font for
-\TeX\ he was using for other kinds of document. Many of the
-\APL\ symbols needed were contained in standard fonts; for example,
-{\it diamond\/} can be found in {\it cmsy10}. For alphanumeric
-characters one could use {\it cmsltt10}. The simplest try for
-a solution of the problem would be to write a list of definitions
-that pick symbols from appropriate fonts. However, this brute force
-method does not really work since these symbols come from
-very different typefaces and, moreover, do not provide a fixed
-typeface. Hence, we decided to find an easy way of producing
-an \APL\ font by using \METAFONT.
-
-As the starting point, we took the font {\it cmtex10}. This is a
-fixed typeface for an extended typewriter-like font including
-some Greek characters and mathematical symbols. The \METAFONT\ file
-for this font, {\sltt cmtex10.mf\/} contains (as usual) a preamble
-that assigns values to several global variables, and the command
-{\sltt generate textset;\/}. Now the {\sl driver\/} file {\sltt textset.mf\/} %@@@@
-contains the commands {\sltt mode\_setup;font\_setup;\/}            %@@@@
-(establishing the values of the variables for this font) and several
-input files from which the \METAFONT\ descriptions of the characters are to
-be found. Since some of these files treat the characters by name and
-since some of the definitions have to be changed (and some dropped),
-we considered it advisable to discard the driver file and to collect
-the separate \METAFONT\ files, together with the preamble, to form a
-large single file {\sltt cmapl10.mf}. The {\sltt .mf\/} character files
-needed for {\sltt cmapl10.mf\/} are the following:
-%
-%
-$$\vbox{\halign{{\sltt#}\hfil && \quad #\hfil\cr
-%
-                      greekl  &  ({\it rho, omega, alpha}) \cr
-                      italms  &  ({\it iota})              \cr
-                      romand  &  (roman digits)            \cr
-                      punct   &  (punctuation symbols)     \cr
-                      romanp  &                            \cr
-                      symbol  &  (math symbols)            \cr
-                      sym     &                            \cr
-                      romanu  &  (uppercase letters)       \cr
-                      romanl  &  (lowercase letters)       \cr

-\section{Definitions}
-\choosett{tentt}%
-The first thing to do is to put {\sltt font\_identifier:="CMAPL";\/}    %@@@@
-and to set {\sltt slant:=0;\/} in the preamble. Many definitions can    %@@@@
-be copied verbatim from the {\sltt .mf\/} files, but some of them
-need changes. The Greek {\it iota}, as given in {\sltt greekl.mf},
-is strange to \APL\ style; we use instead the {\it dotless i\/}
-from {\sltt italms.mf}. Moreover, we used the symbol {\it elt\/}
-(element) from {\sltt sym.mf\/} instead of the Greek {\it epsilon}.
-The symbols {\it del\/} and {\it delta\/} are
-taken from {\sltt symbol.mf\/} (where their names are {\it large triangle\/}
-and {\it large inverted triangle}). However, they are too sturdy
-and too short to be placed in a proper \APL\ font. Further, {\it del\/}
-must be lifted up so that it is vertically aligned with other
-symbols. The modifications are very easy to do, and the modified %@@@@ , by ,and
-definition is shown below.
-%
-%
-\choosett{tentt}
-\begintt
-         % sqrt48 was changed to 6.25 since the del symbol in APL has
-         % a narrower top than the original reversed triangle symbol
-         % rule.nib has been changed to light_rule.nib
-         % bot y3=-d-o has been changed to bot y3=0
-         % top y1=h-d has been changed to top y1=h+2o
-         @null
-         cmchar "Del";
-         beginchar(oct"002",16u#,asc_height#,0);
-         adjust_fit(0,0); pickup light_rule.nib;
-         top y1=h+2o; y2=y1; bot y3=0;
-         .5[x1,x2]=x3=good.x .5w; w:=r:=2x3; lft x1=hround(.5w-u*6.25);
-         draw z1--z2--z3--cycle;    % stroke
-         labels(1,2,3); endchar;
-\endtt
-As can be seen from this example, pen strokes were made thinner.
-Actually only one symbol was directly missing---this is the {\it quad
-box}. However, it can be obtained from the above by adding one control point:
-\begintt
-         cmchar "Quad";
-         beginchar(oct"001",16u#,body_height#,0);
-         adjust_fit(0,0); pickup light_rule.nib;
-         bot y1=0; y2=y1; top y3=h+2o; y4=y3;
-         .5[x1,x2]=x5=good.x .5w; w:=r:=2x5;
-         % The quad box is slightly wider than Del
-         lft x1=hround(.5w-u*7);
-         x3=x1; x4=x2;
-         draw z1--z2--z4--z3--cycle;    % box
-         labels(1,2,3,4); endchar;
-\endtt
-After taking care of special symbols, the letters can be treated
-by finding a suitable value for {\it tilt ratio\/} (slant). Indeed,
-\APL\ letters are {\sl very\/} slanted. We suggest the value
-1/5 for this font (the font {\it cmsl10\/} uses 1/6). One should
-remember to give the command {\sltt font\_setup;\/} after setting {\sltt slant\/} %@@@@
-to 1/5.
-\choosett{sltt}%               %@@@@
-Finally, one has to make the {\it verbatim\/} macros
-suitable for \APL\ style. Since {\it verbatim\/} might be
-used for several different fonts in one document, we decided
-to include a control sequence @\choosett@.
-\choosett{tentt}
-\begintt
-        \def\ifundefined#1{\expandafter\ifx\csname#1\endcsname\relax}
-        \newif\ifapl         \def\aplname{apl}
-        \outer\def\choosett#1{\ifundefined{#1}%
-                \message{Undefined font(?), replaced with cmtt10}%
-                \let\tt=\tentt
-                   \else
-                \def\tt{\expandafter\csname#1\endcsname}%
-                \def\ttname{#1}%
-                \ifx\ttname\aplname\apltrue\else\aplfalse\fi\fi}
-\endtt
-\choosett{sltt}%
-(The control sequence @\ifundefined@ comes from the \TeX{book}, p.\ 308.)
-With the help of @\choosett@, the standard @verbatim@ macros can be used
-with the single change that @\ifapl@, then the @\catcode@ of @A@,\dots,@Z@
-is @\other@ (12) instead of 11 for {\it letter}.  Under \APL\ mode \TeX\
-will then recognize our single-letter control sequences defined, e.g., by
-\choosett{tentt}
-\begintt
-         \def\A#1{\if#1B{\apl\char'174}\else          % stile
-                  \if#1M{\apl\char'004}\fi\fi}        % alpha .
-\endtt
-\choosett{sltt}%
-Unfortunately, we have redefined the standard @\L@, @\O@, @\P@ and @\S@.
-
-The \APL\ symbols not in the font table are obtained---as usual---by
-overstriking two table symbols.
-\choosett{tentt}%
-\begintt
-   \newbox\firstchar\newskip\charwidth
-   \def\overstrike#1#2{\setbox\firstchar=\hbox{#1}\charwidth=\wd\firstchar
-                       #1\hskip-\charwidth#2}
-\endtt
-\choosett{apl}%
-For example, the {\it grade up\/} and {\it grade down\/} symbols
-\G U\ and \G D\ are obtained by striking the {\it stile\/} symbol
-@|@ over \L D\ and \D L, respectively.
-\choosett{tentt}%
-\begintt
-         \def\G#1{\if#1U{\overstrike{\LD}{\AB}}\else      % grade up
-                  \if#1D{\overstrike{\DL}{\AB}}\fi\fi}    % grade down
-\endtt
-Now let us take another example on \APL. The input

-\section{User extension}
-A modern user of a computerized typesetting facility will probably
-ask if it is possible to extend or modify fonts coming with the
-system. As with [5], where the font has an {\it analytic\/} and a
-{\it bitmapped\/} variant, we can distinguish between the need of modifying
-{\it cmapl10\/} via \METAFONT\ and modification of the pixel files.
-\APL\ symbols of various ``blackness'' or ``thickness'' may be desirable.
-Indeed, in [3] the user input is written with boldface \APL\ symbols
-and the answers from the interpreter with thin ones. Furthermore,
-certain screen previewers use specific small size pixel files, and
-do not support the \APL\ font.
-
-The modification of the font by changing the values of some global
-variables in the preamble of the \METAFONT\ file is easy and can be
-done by following how it is done in standard fonts such as
-{\it cmbx10\/} etc. This is the recommended way, too. However, if
-\METAFONT\ is not available, then one must attack the pixel files.
-For direct hand editing, we use a program that converts a pixel
-file into a (bitmapped) text file acceptable to any standard screen
-editor, and another program reading the edited file back into
-a \TeX\ pixel file. Scaling fonts down to a desired size can be
-done in a similar (but automatic) manner; this facility is needed
-by a previewer (written by the first author) not using runtime
-scaling.

-\section{Introduction}
-This note describes an interesting exercise in using
-\METAFONT\ to produce new typefaces by combining letters
-from standard fonts. As we know, the \APL\ language [6] of
-Kenneth Iverson has never gained the popularity it deserves
-which is largely due to its strange symbol set. Indeed,
-true \APL\ users require a special keyboard to support
-the nonstandard but powerful operator symbols. Moreover,
-putting \APL\ into print has always been a problem, and
-modern low cost computerized typesetting programs do
-not usually support \APL\ style. \TeX\ can be used to
-produce high quality printouts for technical text,
-and it would be desirable to have a possibility to
-mix in \APL\ code. The companion program of
-\TeX ---\METAFONT ---provides a full means for a simple generation
-of an \APL\ font for \TeX, and the purpose of this
-note is to inform other people about the result we
-have obtained at the University of Helsinki. Let us note
-that there are at least three other \APL\ fonts available
-for small computer environments. Indeed, the newsletter
-\APL\ {\it Quote Quad\/}\footnote{*}{{\ninepoint Newsletter of SIGAPL,
-the Special Interest Group for \APL. {\it Quote Quad\/} has the same
-status in the world of \APL\ as TUGboat in \TeX{nical} world.}}
-is produced by using TROFF, and there
-exists a Postscript \APL\ font for the Apple Laserwriter [5] and
-another font for the TEXT typesetting system [2].
-
-Consider the following usual kind of function definition in \APL:
-\choosett{apl}
-\begintt
-        @DLS_SUMSQ N;I
-  [1]   S_I_0

-How to write in this code, providing that we have a suitable
-font? The \APL\ font should represent the screen
-output style of \APL\ code and obey the same laws of spacing.
-Hence, it should be a typewriter-like typeface with fixed
-spacing; the same approach for representing \TeX\ input was
-adopted by Knuth in the {\TeX}book.
-The {\it verbatim\/} macros have often been used for importing
-screen or paper outputs into \TeX\ documents; some people
-misuse them for an easy construction of tables etc. In
-{\sltt verbatim}, the typewriter mode is entered by the control
-sequence @\begintt@---that mode is ended by
-@\endtt@. In the same vein, we could enter
-the \APL\ mode by the control sequence @\beginapl@,
-and to end it by @\endapl@. However, it is more convenient to
-augment {\sltt verbatim\/} with {\sltt aplstyle\/} so that
-it can be used with several different typewriter-like fonts.
-(The {\it verbatim\/} macros can be found in the {\TeX}book,
-p.\ 421.)  Since {\sltt\char'100\/}
-(the {\it at sign}) is used as the escape character inside {\it verbatim\/}
-mode, our \TeX\ code might (and in fact does) look as follows:
-\def\endsym{\char'134{endtt}}   % just for using \endtt after \begintt

-The control sequences @\DL@ and @\GO@ are not chosen arbitrarily
-but follow the conventions used in Digital's VAX \APL\ interpreter [1].
-As terminals usually do not support the \APL\ character set, an
-alternative representation by two-letter mnemonics is provided by the
-interpreter. For the most part we have adopted these mnemonics also for our
-\APL\ font. Hence, as an additional bonus the user should find it
-easy to combine his or her \APL\ code with normal \TeX\ code. Thus,
-it is not necessary for a VAX \APL\ user to retype the definitions
-of \APL\ functions in order to be able to use them in documents.
-He or she only has to replace every {\it period\/} used as an
-escape character in Digital's interpreter, by {\sltt\char'100}.
-(There is another syntactical difference between Digital's interpreter
-and \TeX's {\it verbatim\/} mode: for the interpreter
-the third ordinary character after an escape character
-does no longer belong to the escape sequence while \TeX\ admits
-arbitrarily long control sequences.  We take care of this
-by changing certain {\it catcodes\/} temporarily.)

-\section{The \APL\ font table}
-\APL\ symbols are divided into two classes: the primitive symbols
-and those obtained by overstriking two primitive ones. The overstrikes
-are traditionally obtained by typing the first symbol, by using
-backspace to go back one space and then typing the second symbol
-{\sl over\/} the first one. However, in modern \APL\ keyboards these
-double symbols are assigned to non-alphanumeric keys (for example,
-to keys under the {\sltt ALT\/} key). We decided to include only the
-primitive \APL\ symbols in the font table; this enabled us to include
-also the lower-case letters, following modern conventions. (The original
-\APL\ letters were restricted to capitals.) The comment symbol
-@"@ is the only exception since it is keyed in as a double quote.
-Our font is a fixed size typeface with strongly slanted letters.
-Moreover, we have followed the style of best books in \APL:
-all symbols should be drawn with a thin pen to get a touch of
-a typewriter. (This point is clearly witnessed, for example, in [5].)
-The places of some symbols are determined by the \TeX\ font tables.
-For example, the hash sign {\sltt\char'043\/} is used for the
-multiplication sign in VAX \APL, and hence the corresponding symbol
-has the the same octal code (043) as the hash sign in \TeX.
-The font table has the following form:          %@@@@

-\section{The necessary \METAFONT\ files}
-The whole process started when the first author had a paper
-containing \APL\ symbols and was disappointed with the
-quality of the symbols available on the typewriter. Moreover,
-the secretary who had typed the text had forgot a couple
-of lines in the middle of the paper, and the correction of
-such mistakes seemed to be very clumsy in comparison with
-modern typesetting. Then he decided (together with the second
-author) to remedy the situation by creating an \APL\ font for
-\TeX\ he was using for other kinds of document. Many of the
-\APL\ symbols needed were contained in standard fonts; for example,
-{\it diamond\/} can be found in {\it cmsy10}. For alphanumeric
-characters one could use {\it cmsltt10}. The simplest try for
-a solution of the problem would be to write a list of definitions
-that pick symbols from appropriate fonts. However, this brute force
-method does not really work since these symbols come from
-very different typefaces and, moreover, do not provide a fixed
-typeface. Hence, we decided to find an easy way of producing
-an \APL\ font by using \METAFONT.
-
-As the starting point, we took the font {\it cmtex10}. This is a
-fixed typeface for an extended typewriter-like font including
-some Greek characters and mathematical symbols. The \METAFONT\ file
-for this font, {\sltt cmtex10.mf\/} contains (as usual) a preamble
-that assigns values to several global variables, and the command
-{\sltt generate textset;\/}. Now the {\sl driver\/} file {\sltt textset.mf\/} %@@@@
-contains the commands {\sltt mode\_setup;font\_setup;\/}            %@@@@
-(establishing the values of the variables for this font) and several
-input files from which the \METAFONT\ descriptions of the characters are to
-be found. Since some of these files treat the characters by name and
-since some of the definitions have to be changed (and some dropped),
-we considered it advisable to discard the driver file and to collect
-the separate \METAFONT\ files, together with the preamble, to form a
-large single file {\sltt cmapl10.mf}. The {\sltt .mf\/} character files
-needed for {\sltt cmapl10.mf\/} are the following:
-%
-%
-$$\vbox{\halign{{\sltt#}\hfil && \quad #\hfil\cr
-%
-                      greekl  &  ({\it rho, omega, alpha}) \cr
-                      italms  &  ({\it iota})              \cr
-                      romand  &  (roman digits)            \cr
-                      punct   &  (punctuation symbols)     \cr
-                      romanp  &                            \cr
-                      symbol  &  (math symbols)            \cr
-                      sym     &                            \cr
-                      romanu  &  (uppercase letters)       \cr
-                      romanl  &  (lowercase letters)       \cr

-\section{Definitions}
-\choosett{tentt}%
-The first thing to do is to put {\sltt font\_identifier:="CMAPL";\/}    %@@@@
-and to set {\sltt slant:=0;\/} in the preamble. Many definitions can    %@@@@
-be copied verbatim from the {\sltt .mf\/} files, but some of them
-need changes. The Greek {\it iota}, as given in {\sltt greekl.mf},
-is strange to \APL\ style; we use instead the {\it dotless i\/}
-from {\sltt italms.mf}. Moreover, we used the symbol {\it elt\/}
-(element) from {\sltt sym.mf\/} instead of the Greek {\it epsilon}.
-The symbols {\it del\/} and {\it delta\/} are
-taken from {\sltt symbol.mf\/} (where their names are {\it large triangle\/}
-and {\it large inverted triangle}). However, they are too sturdy
-and too short to be placed in a proper \APL\ font. Further, {\it del\/}
-must be lifted up so that it is vertically aligned with other
-symbols. The modifications are very easy to do, and the modified %@@@@ , by ,and
-definition is shown below.
-%
-%
-\choosett{tentt}
-\begintt
-         % sqrt48 was changed to 6.25 since the del symbol in APL has
-         % a narrower top than the original reversed triangle symbol
-         % rule.nib has been changed to light_rule.nib
-         % bot y3=-d-o has been changed to bot y3=0
-         % top y1=h-d has been changed to top y1=h+2o
-         @null
-         cmchar "Del";
-         beginchar(oct"002",16u#,asc_height#,0);
-         adjust_fit(0,0); pickup light_rule.nib;
-         top y1=h+2o; y2=y1; bot y3=0;
-         .5[x1,x2]=x3=good.x .5w; w:=r:=2x3; lft x1=hround(.5w-u*6.25);
-         draw z1--z2--z3--cycle;    % stroke
-         labels(1,2,3); endchar;
-\endtt
-As can be seen from this example, pen strokes were made thinner.
-Actually only one symbol was directly missing---this is the {\it quad
-box}. However, it can be obtained from the above by adding one control point:
-\begintt
-         cmchar "Quad";
-         beginchar(oct"001",16u#,body_height#,0);
-         adjust_fit(0,0); pickup light_rule.nib;
-         bot y1=0; y2=y1; top y3=h+2o; y4=y3;
-         .5[x1,x2]=x5=good.x .5w; w:=r:=2x5;
-         % The quad box is slightly wider than Del
-         lft x1=hround(.5w-u*7);
-         x3=x1; x4=x2;
-         draw z1--z2--z4--z3--cycle;    % box
-         labels(1,2,3,4); endchar;
-\endtt
-After taking care of special symbols, the letters can be treated
-by finding a suitable value for {\it tilt ratio\/} (slant). Indeed,
-\APL\ letters are {\sl very\/} slanted. We suggest the value
-1/5 for this font (the font {\it cmsl10\/} uses 1/6). One should
-remember to give the command {\sltt font\_setup;\/} after setting {\sltt slant\/} %@@@@
-to 1/5.
-\choosett{sltt}%               %@@@@
-Finally, one has to make the {\it verbatim\/} macros
-suitable for \APL\ style. Since {\it verbatim\/} might be
-used for several different fonts in one document, we decided
-to include a control sequence @\choosett@.
-\choosett{tentt}
-\begintt
-        \def\ifundefined#1{\expandafter\ifx\csname#1\endcsname\relax}
-        \newif\ifapl         \def\aplname{apl}
-        \outer\def\choosett#1{\ifundefined{#1}%
-                \message{Undefined font(?), replaced with cmtt10}%
-                \let\tt=\tentt
-                   \else
-                \def\tt{\expandafter\csname#1\endcsname}%
-                \def\ttname{#1}%
-                \ifx\ttname\aplname\apltrue\else\aplfalse\fi\fi}
-\endtt
-\choosett{sltt}%
-(The control sequence @\ifundefined@ comes from the \TeX{book}, p.\ 308.)
-With the help of @\choosett@, the standard @verbatim@ macros can be used
-with the single change that @\ifapl@, then the @\catcode@ of @A@,\dots,@Z@
-is @\other@ (12) instead of 11 for {\it letter}.  Under \APL\ mode \TeX\
-will then recognize our single-letter control sequences defined, e.g., by
-\choosett{tentt}
-\begintt
-         \def\A#1{\if#1B{\apl\char'174}\else          % stile
-                  \if#1M{\apl\char'004}\fi\fi}        % alpha .
-\endtt
-\choosett{sltt}%
-Unfortunately, we have redefined the standard @\L@, @\O@, @\P@ and @\S@.
-
-The \APL\ symbols not in the font table are obtained---as usual---by
-overstriking two table symbols.
-\choosett{tentt}%
-\begintt
-   \newbox\firstchar\newskip\charwidth
-   \def\overstrike#1#2{\setbox\firstchar=\hbox{#1}\charwidth=\wd\firstchar
-                       #1\hskip-\charwidth#2}
-\endtt
-\choosett{apl}%
-For example, the {\it grade up\/} and {\it grade down\/} symbols
-\G U\ and \G D\ are obtained by striking the {\it stile\/} symbol
-@|@ over \L D\ and \D L, respectively.
-\choosett{tentt}%
-\begintt
-         \def\G#1{\if#1U{\overstrike{\LD}{\AB}}\else      % grade up
-                  \if#1D{\overstrike{\DL}{\AB}}\fi\fi}    % grade down
-\endtt

-\section{User extension}
-A modern user of a computerized typesetting facility will probably
-ask if it is possible to extend or modify fonts coming with the
-system. As with [5], where the font has an {\it analytic\/} and a
-{\it bitmapped\/} variant, we can distinguish between the need of modifying
-{\it cmapl10\/} via \METAFONT\ and modification of the pixel files.
-\APL\ symbols of various ``blackness'' or ``thickness'' may be desirable.
-Indeed, in [3] the user input is written with boldface \APL\ symbols
-and the answers from the interpreter with thin ones. Furthermore,
-certain screen previewers use specific small size pixel files, and
-do not support the \APL\ font.
-
-The modification of the font by changing the values of some global
-variables in the preamble of the \METAFONT\ file is easy and can be
-done by following how it is done in standard fonts such as
-{\it cmbx10\/} etc. This is the recommended way, too. However, if
-\METAFONT\ is not available, then one must attack the pixel files.
-For direct hand editing, we use a program that converts a pixel
-file into a (bitmapped) text file acceptable to any standard screen
-editor, and another program reading the edited file back into
-a \TeX\ pixel file. Scaling fonts down to a desired size can be
-done in a similar (but automatic) manner; this facility is needed
-by a previewer (written by the first author) not using runtime
-scaling.
