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.

T X T -%================================================================= - - 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. - diff --git a/Master/texmf-dist/source/fonts/apl/sample.tex b/Master/texmf-dist/source/fonts/apl/sample.tex deleted file mode 100644 index 85481d7c943..00000000000 --- a/Master/texmf-dist/source/fonts/apl/sample.tex +++ /dev/null @@ -1,124 +0,0 @@ - -%============================================================================ -% S A M P L E .

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 -\choosett{tentt} -\begintt - \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 - @endsym -\endtt -\choosett{sltt}% %@@@@ -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.) -% -% -\choosett{apl}% -% -\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: %@@@@ - -%======================================================================== -% table begins -%======================================================================== -% This macro comes from TUGboat (I (AH) do not remember which number), -% unsuitable parts are commented out. -% -{\baselineskip=0pt \lineskip=0pt -\newdimen\vu -% -%\output={\shipout\vbox{\unvbox255\vskip0.4in}\advancepageno} -% -\setbox9=\hbox{\sl 0} -\def\spike{\hbox to 0pt{\vbox to \ht9{}}} -\def\cell#1{\hbox to 1\vu{\hfill\char'#1\hfill}\vrule} -\def\label#1{\vbox to \ht8{\vfill\hbox to 35pt{\hfill\sl '#10\hskip1em% - }\vfill}\vrule} -% -\def\seprow{\def\m{\hskip 1\vu{}\vrule height 2pt}\hbox{\m\m\m\m\m\m\m\m}} -\def\cellrow#1{\setbox8=\vbox{\seprow\hbox{\spike% - \cell{#10}\cell{#11}\cell{#12}\cell{#13}% - \cell{#14}\cell{#15}\cell{#16}\cell{#17}\hfill% - }\seprow\hrule}\hbox{\label{#1}\box8}} -% -\def\lcol#1{\hbox to 1\vu{\hfill{\sl #1}\hfill}\hskip .4pt} -\def\chw#1{\hbox{\char'#1}} -% -\def\colw#1{\vbox{\chw{#10} - \chw{#11} - \chw{#12} - \chw{#13} - \chw{#14} - \chw{#15} - \chw{#16} - \chw{#17}}} -% -\def\setw#1{\vbox{\colw{#10} - \colw{#11} - \colw{#12} - \colw{#13} - \colw{#14} - \colw{#15} - \colw{#16} - \colw{#17}}} -% -\def\getw{\setbox0=\vbox{\setw0\setw1\hbox to \wd9{}\hbox to 1em{}}% - \vu=1.625\wd0} -% - \apl\getw\bigskip % changed from \null\vfill to \bigskip -% - \centerline{\vbox{%\hbox{\hskip35pt{\sl cmapl10}\hfill} -% \vskip20pt - \hbox{\hskip35pt\lcol0\lcol1\lcol2\lcol3\lcol4\lcol5\lcol6\lcol7} - \vskip 4pt - \hbox{\hskip35pt\vbox{\hrule width 8\vu}\vbox{\hrule width 3.6pt}} - \cellrow{00}\cellrow{01}\cellrow{02}\cellrow{03} - \cellrow{04}\cellrow{05}\cellrow{06}\cellrow{07} - \cellrow{10}\cellrow{11}\cellrow{12}\cellrow{13} - \cellrow{14}\cellrow{15}\cellrow{16}\cellrow{17}}}} % removed \vfill -% % from the end -% -%======================================================================== -% table ends -%======================================================================== -% -\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.

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 -\choosett{tentt} -\begintt - \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 - @endsym -\endtt -\choosett{sltt}% %@@@@ -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.) -% -% -\choosett{apl}% -% -\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: %@@@@ - -%======================================================================== -% table begins -%======================================================================== -% This macro comes from TUGboat (I (AH) do not remember which number), -% unsuitable parts are commented out. -% -{\baselineskip=0pt \lineskip=0pt -\newdimen\vu -% -%\output={\shipout\vbox{\unvbox255\vskip0.4in}\advancepageno} -% -\setbox9=\hbox{\sl 0} -\def\spike{\hbox to 0pt{\vbox to \ht9{}}} -\def\cell#1{\hbox to 1\vu{\hfill\char'#1\hfill}\vrule} -\def\label#1{\vbox to \ht8{\vfill\hbox to 35pt{\hfill\sl '#10\hskip1em% - }\vfill}\vrule} -% -\def\seprow{\def\m{\hskip 1\vu{}\vrule height 2pt}\hbox{\m\m\m\m\m\m\m\m}} -\def\cellrow#1{\setbox8=\vbox{\seprow\hbox{\spike% - \cell{#10}\cell{#11}\cell{#12}\cell{#13}% - \cell{#14}\cell{#15}\cell{#16}\cell{#17}\hfill% - }\seprow\hrule}\hbox{\label{#1}\box8}} -% -\def\lcol#1{\hbox to 1\vu{\hfill{\sl #1}\hfill}\hskip .4pt} -\def\chw#1{\hbox{\char'#1}} -% -\def\colw#1{\vbox{\chw{#10} - \chw{#11} - \chw{#12} - \chw{#13} - \chw{#14} - \chw{#15} - \chw{#16} - \chw{#17}}} -% -\def\setw#1{\vbox{\colw{#10} - \colw{#11} - \colw{#12} - \colw{#13} - \colw{#14} - \colw{#15} - \colw{#16} - \colw{#17}}} -% -\def\getw{\setbox0=\vbox{\setw0\setw1\hbox to \wd9{}\hbox to 1em{}}% - \vu=1.625\wd0} -% - \apl\getw\bigskip % changed from \null\vfill to \bigskip -% - \centerline{\vbox{%\hbox{\hskip35pt{\sl cmapl10}\hfill} -% \vskip20pt - \hbox{\hskip35pt\lcol0\lcol1\lcol2\lcol3\lcol4\lcol5\lcol6\lcol7} - \vskip 4pt - \hbox{\hskip35pt\vbox{\hrule width 8\vu}\vbox{\hrule width 3.6pt}} - \cellrow{00}\cellrow{01}\cellrow{02}\cellrow{03} - \cellrow{04}\cellrow{05}\cellrow{06}\cellrow{07} - \cellrow{10}\cellrow{11}\cellrow{12}\cellrow{13} - \cellrow{14}\cellrow{15}\cellrow{16}\cellrow{17}}}} % removed \vfill -% % from the end -% -%======================================================================== -% table ends -%======================================================================== -% -\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.

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{References} -\bigskip -{ -\ref Digital Equipment Corporation: VAX-11 \APL\ Reference Manual.- - 1983. - -\ref Feldberg, Ian: TEXT: Publication-Quality Characters Come - to \APL\ Graphics.- Proceedings of the 1986 \APL\ Conference, - SIGAPL, pp.\ 306--313. - -\ref Gilman, Leonard, and Allen J.\ Rose: \APL, An Interactive - Approach.- John Wiley \& Sons, Inc., 1984. - -\ref Grenander, Ulf: Mathematical Experiments on the Computer.- - Academic Press, 1982. - -\ref Howland, John E.: Typesetting \APL\ Using a Macintosh.- - Proceedings of the 1986 \APL\ Conference, SIGAPL, pp.\ 301--305. - -\ref Iverson, Kenneth: A Programming Language.- Wiley, New York, 1962. - - - } - -\bigskip -\section{The address} -\bigskip -{\ninepoint\obeylines -\hskip\refskip University of Helsinki -\hskip\refskip Department of Mathematics -\hskip\refskip Hallituskatu 15 -\hskip\refskip SF--00100 HELSINKI -\hskip\refskip FINLAND -} - -\end - - -%============================================================================ -% -%============================================================================ diff --git a/Master/texmf-dist/source/fonts/apl/versatim.tex b/Master/texmf-dist/source/fonts/apl/versatim.tex deleted file mode 100644 index c2ff320a7e5..00000000000 --- a/Master/texmf-dist/source/fonts/apl/versatim.tex +++ /dev/null @@ -1,66 +0,0 @@ - -%============================================================================= -% V E R S A T I M .
