+web2c/triptrap -- The trip and trap tests are Knuth's torture tests for
+TeX and Metafont.  The MetaPost test is also named `trap', so I've
+renamed the conflicting files to `mftrap...' and `mptrap...'.  (The
+contents of all files remain absolutely unaltered, of course.)
+
+The tests are exercised in the web2c distribution via `make trip trap mptrap'
+(from the top-level or web2c/ directories).  They do not and cannot
+exercise the path searching capabilities; for that, a few ``normal''
+test runs before and after installation should suffice.
+
+{trip,mftrap,mptrap}.diffs -- show the diffs from Knuth's originals as
+generated on my development machine. tripman.tex, trapman.tex, and
+mptrap.readme explain precisely what is and is not acceptable.
+Generally, for trap and MetaPost trap, dates and times, a number of
+  constants and one call to BLANKRECTANGLE will be different.
+For trip, again some constants will be different. The floating point
+  numbers in glue set ratios may be slightly different (but all the box
+  dimensions must be the same), and the y* and down* commands in the
+  trip.dvi file may be somewhat different. The hyphenation exceptions
+  are different because the exception routine now does not count
+  identical hyphenations separately, i.e., \hyphenation{a-a a-a} only
+  generates one exception in the table.  See the messages below for why
+  this is a good/necessary thing (if the hyphenation exception table is
+  to be dynamic at all).
+
+texmf.cnf -- sets up various constants the way the tests want them.  Not
+all constants can be changed, alas, but this suffices to avoid building
+a separate binary just to run the tests.
+
+*.in -- fed to the programs as standard input, to avoid manual intervention.
+
+All the other files are test sources and output.
+It's a mistake to change them.
+
+
+About the hyphenation exception thing:

+Subject: Re: hyph_size +1
+
+Upon consideration I found another change needed for dynamic hyph_size.
+Actually, it is one I used earlier but removed for the sake of the trip.log.
+Knuth's treatment of hyhpenation exceptions has an unpleasant "feature"
+in that if the same "word" is given in \hyphenation{...}, the code does not
+replace the existing entry, but adds a new entry which comes before all
+other entries of the specific "word" (which includes the language code
+as its last "letter"), so that the earlier entries are inaccessible. The
+point is that the exceptions table retains useless data. 
+Try this with the current version of TeX:
+        \hyphenation{ab ab ab ab ... ab ab}
+Use any word you like for "ab" so long as it has at least two letters. With
+\tracingstats>0, you get lots of hyphen exceptions, but only the last for
+"ab" is accessible. I could copy this behavior using a simple hash code,
+but it seems [pointless]. Instead, when a word is repeated in "\hyphenation"
+the new code simply replaces the old entry, so no extra space in the
+exception tables is consumed. Since there is no way to recover the previous
+entry for a hyphenation exception which has been superseded, I can see no
+point in keeping the old data. The location of hyphens is kept as a linked
+list in TeX's mem array. This data for a superseded hyphenation exception
+could also be flushed, but it makes more differences in trip.log because
+the memory stats are different. These entries are unlikely to consume much
+space, so there is little harm in leaving them.
+
+Anyway the additional change needed corresponds to the following:
+
+diff -c tex.ch.old tex.ch
+*** tex.ch.old  Fri Mar 29 17:25:28 1996
+--- tex.ch      Mon Apr  1 10:08:54 1996
+***************
+*** 2177,2182 ****
+--- 2177,2183 ----
+  until u=str_start[k+1];
+  {repeat hyphenation exception; flushing old data}
+  flush_string; s:=hyph_word[h]; {avoid |slow_make_string|!}
++ decr(hyph_count);
+  { We could also |flush_list(hyph_list[h]);|, but it interferes
+    with the trip.log. }
+  goto found;
+
+Thus it is only additional change is to decrement the hyph_count when a
+repeat hyphenation exception is encountered. This is really essential only
+for the "ini" version. The reason is to know exactly how many hyphenation
+exceptions to undump. The change might as well be included in all versions,
+because it handles repeated hyphenation exceptions in a more efficient way
+than the original code. I checked through trip.tex. There is only one word
+included in hyphenation exceptions, but it is given two different hyphenations.
+Thus the original trip.log states 2 hyphenation exceptions, while the one
+using simple hashing shows only 1 -- the single exception has been entered
+twice.

+The `trap' test for MetaPost is analogous to the similarly named test for
+METAFONT.  It requires a special version of inimp with the following constant
+settings:
+    mem_max = 4500+mem_min
+    error_line = 64
+    half_error_line = 32
+    max_print_line = 72
+    mem_top = 4500+mem_min
+The other parameters max_internal, buf_size, etc. are not very important but
+should be left at the values given in mp.web if possible.
+
+The trap test uses mtrap.mp trap.mp, trap.mpx, and trapf.tfm.  These four files
+should be in the current directory when running the trap test; the other files in
+this directory should be saved for comparison purposes.  Be sure that trap.mpx
+is written more recently than trap.mp so that MetaPost does not try to
+regenerate trap.mpx.
+
+Run the special inimp on mtrap.mp.  It should generate mtrap.log, mtrap.0,
+mtrap.1, writeo, and writeo.2.  They should almost match the corresponding files
+in this directory except that mtrap.log can have the `allowable differences'
+listed below.  (The other output files can only differ in their `%%CreationDate'
+lines.)
+
+Run the special inimp and give it the contents of trap1.in as terminal input.
+This should produce lots of error messages and write a binary file `trap.mem'.
+The resulting trap.log should almost match the trapin.log in this directory.
+
+Now run the special inimp again and give it the contents of trap2.in as terminal
+input.  The terminal output should almost match trap.fot and the other files
+written should almost match the versions in this directory.  Run the binary
+output file trap.tfm through tftopl and compare the resulting trap.pl with the
+one in this directory.
+
+                            Allowable differences
+1. trap.log, trap.ps, and the output files with numeric extensions all contain
+   lines that give the time and date.
+
+2. The capacity values printed out at the end depend on the parameters buf_size,
+   stack_size, etc.
+
+3. The strings `now untouched' statistics may differ due to changes in the
+   number of characters in the date on the first line of the log file.  All the
+   string statistics will change if you alter ../mp.ch in a way that changes the
+   string pool.
+
+4. If integer division with negative numbers does not truncate toward zero in
+   your implementation, numeric results will be rounded differently.
+
+5. If for some reason you alter the storage allocation code ../mp.web or ../mp.ch
+   this will change the memory usage statistics and the capsule numbers.

+\section Introduction.
+People often think that their programs are ``debugged'' when large applications
+have been run successfully. But system programmers know that a typical large
+application tends to use at most about 50 per cent of the instructions
+in a typical compiler. Although the other half of the code---which tends
+to be the ``harder half''---might be riddled with errors, the system seems
+to be working quite impressively until an unusual case shows up on the
+next day. And on the following day another error manifests itself, and so on;
+months or years go by before certain parts of the compiler are even
+activated, much less tested in combination with other portions of the system,
+if user applications provide the only tests.
+
+How then shall we go about testing a compiler? Ideally we would like to
+have a formal proof of correctness, certified by a computer.
+This would give us a lot of confidence,
+although of course the formal verification program might itself be incorrect.
+A more serious drawback of automatic verification is that the formal
+specifications of the compiler are likely to be wrong, since they aren't
+much easier to write than the compiler itself. Alternatively, we can
+substitute an informal proof of correctness: The programmer writes his or
+her code in a structured manner and checks that appropriate relations
+remain invariant, etc. This helps greatly to reduce errors, but it cannot
+be expected to remove them completely; the task of checking a large
+system is sufficiently formidable that human beings cannot do it without
+making at least a few slips here and there.
+
+Thus, we have seen that test programs are unsatisfactory if they are simply
+large user applications; yet some sort of test program is needed because
+proofs of correctness aren't adequate either. People have proposed schemes
+for constructing test data automatically from a program text, but such
+approaches run the risk of circularity, since they cannot assume that a
+given program has the right structure.
+
+I have been having good luck with a somewhat different approach,
+first used in 1960 to debug an {\mc ALGOL} compiler. The idea is to
+construct a test file that is about as different from a typical user
+application as could be imagined. Instead of testing things that people
+normally want to do, the file tests complicated things that people would
+never dare to think of, and it embeds these complexities in still
+more arcane constructions. Instead of trying to make the compiler do the
+right thing, the goal is to make it fail (until the bugs have all been found).
+
+To write such a fiendish test routine, one simply gets into a nasty frame
+of mind and tries to do everything in the unexpected way. Parameters
+that are normally positive are set negative or zero; borderline cases
+are pushed to the limit; deliberate errors are made in hopes that the
+compiler will not be able to recover properly from them.
+
+A user's application tends to exercise 50\%\ of a compiler's logic,
+but my first fiendish tests tend to improve this to about 90\%. As the
+next step I generally make use of frequency-counting software to identify
+the instructions that have still not been called upon. Then I add ever more
+fiendishness to the test routine, until more than 99\%\ of the code
+has been used at least once. (The remaining bits are things that
+can occur only if the source program is really huge, or if certain
+fatal errors are detected; or they are cases so similar to other well-tested
+things that there can be little doubt of their validity.)
+
+Of course, this is not guaranteed to work. But my experience in 1960 was
+that only two bugs were ever found in that {\mc ALGOL} compiler after it
+correctly translated that original fiendish test. And one of those bugs
+was actually present in the results of the test; I simply had failed to
+notice that the output was incorrect. Similar experiences occurred later
+during the 60s and 70s, with respect to a few assemblers, compilers,
+and simulators that I wrote.
+
+This method of debugging, combined with the methodology of structured
+programming and informal proofs (otherwise known as careful desk checking),
+leads to greater reliability of production software than any other
+method I know. Therefore I have used it in developing \MF84, and the
+main bulk of this report is simply a presentation of the test program
+that was used to get the bugs out of \MF.
+
+Such a test file is useful also after a program has been debugged, since
+it can be used to give some assurance that subsequent modifications don't
+mess things up.
+
+The test file is called \.{TRAP.MF}, because of my warped sense of humor:
+\MF's companion system, \TeX, has a similar test file called \.{TRIP}, and I
+couldn't help thinking about Billy Goat Gruff and the story of ``trip,
+trap, trip, trap.''
+
+The contents of this test file are so remote from what people actually
+do with \MF, I feel apologetic if I have to explain the correct
+translation of \.{TRAP.MF}; nobody really cares about most of the
+nitty-gritty rules that are involved. Yet I believe \.{TRAP} exemplifies
+the sort of test program that has outstanding diagnostic ability, as
+explained above.
+
+If somebody claims to have a correct implementation of \MF, I will not
+believe it until I see that \.{TRAP.MF} is translated properly.
+I propose, in fact, that a program must meet two criteria before it
+can justifiably be called \MF: (1)~The person who wrote it must be
+happy with the way it works at his or her installation; and (2)~the
+program must produce the correct results from \.{TRAP.MF}.
+
+\MF\ is in the public domain, and its algorithms are published;
+I've done this since I do not want to discourage its use by placing
+proprietary restrictions on the software. However, I don't want
+faulty imitations to masquerade as \MF\ processors, since users
+want \MF\ to produce identical results on different machines.
+Hence I am planning to do whatever I can to suppress any systems that
+call themselves \MF\ without meeting conditions (1) and~(2).
+I have copyrighted the programs so that I have some chance to forbid
+unauthorized copies; I explicitly authorize copying of correct
+\MF\ implementations, and not of incorrect ones!
+
+The remainder of this report consists of appendices, whose contents ought
+to be described briefly here:
+
+Appendix A explains in detail how to carry out a test of \MF, given
+a tape that contains copies of the other appendices.
+
+Appendix B is \.{TRAP.MF}, the fiendish test file that has already
+been mentioned. People who think that they understand \MF\ are challenged
+to see if they know what \MF\ is supposed to do with this file.
+People who know only a little about \MF\ might still find it
+interesting to study Appendix~B, just to get some insights into the
+methodology advocated here.
+
+Appendix C is \.{TRAPIN.LOG}, a correct transcript file \.{TRAP.LOG}
+that results if \.{INIMF} is applied to \.{TRAP.MF}. (\.{INIMF} is
+the name of a version of \MF\ that does certain initializations;
+this run of \.{INIMF} also creates a binary base file called \.{TRAP.BASE}.)
+
+Appendix D is a correct transcript file \.{TRAP.LOG} that results if
+\.{INIMF} or any other version of \MF\ is applied to \.{TRAP.MF}
+with base file \.{TRAP.BASE}.
+
+Appendix E is \.{TRAP.TYP}, the symbolic version of a correct output
+file \.{TRAP.72270GF} that was produced at the same time as the \.{TRAP.LOG}
+file of Appendix~D.
+
+Appendix F is \.{TRAP.PL}, the symbolic version of a correct output
+file \.{TRAP.TFM} that was produced at the same time as the \.{TRAP.LOG}
+file of Appendix~D.
+
+Appendix G is \.{TRAP.FOT}, an abbreviated version of Appendix D that
+appears on the user's terminal during the run that produces \.{TRAP.LOG},
+\.{TRAP.72270GF}, and \.{TRAP.TFM}.
+
+The debugging of \MF\ and the testing of the adequacy of \.{TRAP.MF}
+could not have been done nearly as well as reported here except for
+the magnificent software support provided by my colleague David R. Fuchs.
+In particular, he extended our local Pascal compiler so that
+frequency counting and a number of other important features were added
+to its online debugging abilities.
+
+The method of testing advocated here has one chief difficulty that deserves
+comment: I had to verify by hand that \MF\ did the right things
+to \.{TRAP.MF}. This took many hours, and perhaps I have missed
+something (as I did in 1960); I must confess that I have not checked
+every single number in Appendices D, E, and~F. However, I'm willing to pay
+$\$$81.92 to the first finder of any remaining bug in \MF, and I will
+be surprised if that bug doesn't show up also in one of these appendices.
+

+
+\section Appendix A: How to test \MF.
+
+\item{0.} Let's assume that you have a tape containing \.{TRAP.MF},
+\.{TRAPIN.LOG}, \.{TRAP.LOG}, \.{TRAP.TYP}, \.{TRAP.PL}, and \.{TRAP.FOT},
+as in Appendices B, C, D, E, F, and~G. Furthermore, let's suppose that you
+have a working \.{WEB} system, and that you have working programs
+\.{TFtoPL} and \.{GFtype}, as described in the \TeX ware and \MF ware reports.
+
+\item{1.} Prepare a version of \.{INIMF}. (This means that your \.{WEB}
+change file should have {\bf init} and {\bf tini} defined to be null.)
+The {\bf debug} and {\bf gubed} macros should be null, in order to
+activate special printouts that occur when $\\{tracingedges}>1.0$.
+The {\bf stat} and {\bf tats} macros should also be null, so that
+statistics are kept. Set \\{mem\_top} and \\{mem\_max} to 3000
+(or to \\{mem\_min} plus 3000, if \\{mem\_min} isn't zero),
+for purposes of this test version.
+Also set $\\{error\_line}=64$, $\\{half\_error\_line}=32$,
+$\\{max\_print\_line}=72$, $\\{screen\_width}=100$, and
+$\\{screen\_depth}=200$; these parameters affect many of the lines of
+the test output, so your job will be much easier if you use the same
+settings that were used to produce Appendix~E. Also (if possible) set
+$\\{gf\_buf\_size}=8$, since this tests more parts of the program.
+You probably should also use the ``normal'' settings of other parameters
+found in \.{MF.WEB} (e.g., $\\{max\_internal}=100$, $\\{buf\_size}=500$,
+etc.), since these show up in a few lines of the test output. Finally,
+change \MF's screen-display routines by putting the following simple lines
+in the change file:
+$$\vbox{\halign{\tt#\hfil\cr
+\char`\@x Screen routines:\cr
+begin init\char`\_screen:=false;\cr
+\char`\@y\cr
+begin init\char`\_screen:=true;
+ \char`\{screen instructions will be logged\char`\}\cr
+\char`\@z\cr}}$$
+None of the other screen routines (\\{update\_screen}, \\{blank\_rectangle},
+\\{paint\_row}) should be changed in any way; the effect will be to have
+\MF's actions recorded in the transcript files instead of on the screen,
+in a machine-independent way.
+
+\item{2.} Run the \.{INIMF} prepared in step 1. In response to the first
+`\.{**}' prompt, type carriage return (thus getting another `\.{**}').
+Then type `\.{\char`\\input trap}'. You should get an output that matches
+the file \.{TRAPIN.LOG} (Appendix~C). Don't be alarmed by the error
+messages that you see, unless they are different from those in Appendix~C.
+
+\def\sp{{\char'40}}
+\item{3.} Run \.{INIMF} again. This time type `\.{\sp\&trap\sp\sp trap\sp}'.
+(The spaces in this input help to check certain parts of \MF\ that
+aren't otherwise used.) You should get outputs \.{TRAP.LOG}, \.{TRAP.72270GF},
+and \.{TRAP.TFM}.
+Furthermore, your terminal should receive output that matches \.{TRAP.FOT}
+(Appendix~G). During the middle part of this test, however, the terminal
+will not be getting output, because \.{batchmode} is being
+tested; don't worry if nothing seems to be happening for a while---nothing
+is supposed to.
+
+\item{4.} Compare the \.{TRAP.LOG} file from step 3 with the ``master''
+\.{TRAP.LOG} file of step~0. (Let's hope you put that master file in a
+safe place so that it wouldn't be clobbered.) There should be perfect
+agreement between these files except in the following respects:
+
+\itemitem{a)} The dates and possibly the file names will
+naturally be different.
+
+\itemitem{b)} If you had different values for \\{stack\_size}, \\{buf\_size},
+etc., the corresponding capacity values will be different when they
+are printed out at the end.
+
+\itemitem{c)} Help messages may be different; indeed, the author encourages
+non-English help messages in versions of \MF\ for people who don't
+understand English as well as some other language.
+
+\itemitem{d)} The total number and length of strings at the end and/or
+``still untouched'' may well be different.
+
+\itemitem{e)} If your \MF\ uses a different memory allocation or
+packing scheme, the memory usage statistics may change.
+
+\itemitem{f)} If you use a different storage allocation scheme, the
+capsule numbers will probably be different, but the order of variables
+should be unchanged when dependent variables are shown. \MF\ should also
+choose the same variables to be dependent.
+
+\itemitem{g)} If your computer handles integer division of negative operands
+in a nonstandard way, you may get results that are rounded differently.
+Although \TeX\ is careful to be machine-independent in this regard,
+\MF\ is not, because integer divisions are present in so many places.
+
+\item{5.} Use \.{GFtype} to convert your file \.{TRAP.72270GF} to a file
+\.{TRAP.TYP}. (Both of \.{GFtype}'s options, i.e., mnemonic output and image
+output, should be enabled so that you get the maximum amount of output.)
+The resulting file should agree with the master \.{TRAP.TYP} file of step~0,
+assuming that your \.{GFtype} has the ``normal'' values of compile-time
+constants ($\\{top\_pixel}=69$, etc.).
+
+\item{6.} Use \.{TFtoPL} to convert your file \.{TRAP.TFM} to a file
+\.{TRAP.PL}. The resulting file should agree with the master \.{TRAP.PL}
+file of step~0.
+
+\item{7.} You might also wish to test \.{TRAP} with other versions of
+\MF\ (i.e., \.{VIRMF} or a production version with another base file
+preloaded). It should work unless \MF's primitives have been redefined in
+the base file. However, this step isn't essential, since all the code of
+\.{VIRMF} appears in \.{INIMF}; you probably won't catch any more errors
+this way, unless they would already become obvious from normal use of
+the~system.

+The paragraph just ended includes some glue that has
+infinite shrinkability, e.g., `\hskip 0pt minus 1fil'.
+Such glue doesn't belong there---it allows a paragraph
+of any length to fit on one line. But it's safe to proceed,
+since the offensive shrinkability has been made finite.

+The control sequence at the end of the top line
+of your error message was never \def'ed. If you have
+misspelled it (e.g., `\hobx'), type `I' and the correct

+\section Introduction.
+People often think that their programs are ``debugged'' when large applications
+have been run successfully. But system programmers know that a typical large
+application tends to use at most about 50 per cent of the instructions
+in a typical compiler. Although the other half of the code---which tends
+to be the ``harder half''---might be riddled with errors, the system seems
+to be working quite impressively until an unusual case shows up on the
+next day. And on the following day another error manifests itself, and so on;
+months or years go by before certain parts of the compiler are even
+activated, much less tested in combination with other portions of the system,
+if user applications provide the only tests.
+
+How then shall we go about testing a compiler? Ideally we would like to
+have a formal proof of correctness, certified by a computer.
+This would give us a lot of confidence,
+although of course the formal verification program might itself be incorrect.
+A more serious drawback of automatic verification is that the formal
+specifications of the compiler are likely to be wrong, since they aren't
+much easier to write than the compiler itself. Alternatively, we can
+substitute an informal proof of correctness: The programmer writes his or
+her code in a structured manner and checks that appropriate relations
+remain invariant, etc. This helps greatly to reduce errors, but it cannot
+be expected to remove them completely; the task of checking a large
+system is sufficiently formidable that human beings cannot do it without
+making at least a few slips here and there.
+
+Thus, we have seen that test programs are unsatisfactory if they are simply
+large user applications; yet some sort of test program is needed because
+proofs of correctness aren't adequate either. People have proposed schemes
+for constructing test data automatically from a program text, but such
+approaches run the risk of circularity, since they cannot assume that a
+given program has the right structure.
+
+I have been having good luck with a somewhat different approach,
+first used in 1960 to debug an {\mc ALGOL} compiler. The idea is to
+construct a test file that is about as different from a typical user
+application as could be imagined. Instead of testing things that people
+normally want to do, the file tests complicated things that people would
+never dare to think of, and it embeds these complexities in still
+more arcane constructions. Instead of trying to make the compiler do the
+right thing, the goal is to make it fail (until the bugs have all been found).
+
+To write such a fiendish test routine, one simply gets into a nasty frame
+of mind and tries to do everything in the unexpected way. Parameters
+that are normally positive are set negative or zero; borderline cases
+are pushed to the limit; deliberate errors are made in hopes that the
+compiler will not be able to recover properly from them.
+
+A user's application tends to exercise 50\%\ of a compiler's logic,
+but my first fiendish tests tend to improve this to about 90\%. As the
+next step I generally make use of frequency-counting software to identify
+the instructions that have still not been called upon. Then I add ever more
+fiendishness to the test routine, until more than 99\%\ of the code
+has been used at least once. (The remaining bits are things that
+can occur only if the source program is really huge, or if certain
+fatal errors are detected; or they are cases so similar to other well-tested
+things that there can be little doubt of their validity.)
+
+Of course, this is not guaranteed to work. But my experience in 1960 was
+that only two bugs were ever found in that {\mc ALGOL} compiler after it
+correctly translated that original fiendish test. And one of those bugs
+was actually present in the results of the test; I simply had failed to
+notice that the output was incorrect. Similar experiences occurred later
+during the 60s and 70s, with respect to a few assemblers, compilers,
+and simulators that I wrote.
+
+This method of debugging, combined with the methodology of structured
+programming and informal proofs (otherwise known as careful desk checking),
+leads to greater reliability of production software than any other
+method I know. Therefore I have used it in developing \TeX82, and the
+main bulk of this report is simply a presentation of the test program
+that was used to get the bugs out of \TeX.
+
+Such a test file is useful also after a program has been debugged, since
+it can be used to give some assurance that subsequent modifications don't
+mess things up.
+
+The test file is called \.{TRIP.TEX}, because of my warped sense of humor:
+\TeX\ is pronounced ``techhh'', so the name reminded me of a
+triptych (and besides, I wanted to take a trip through the program while
+tripping it up, etc.).
+
+The contents of this test file are so remote from what people actually
+do with \TeX, I feel apologetic if I have to explain the correct
+translation of \.{TRIP.TEX}; nobody really cares about most of the
+nitty-gritty rules that are involved. Yet I believe \.{TRIP} exemplifies
+the sort of test program that has outstanding diagnostic ability, as
+explained above.
+
+If somebody claims to have a correct implementation of \TeX, I will not
+believe it until I see that \.{TRIP.TEX} is translated properly.
+I propose, in fact, that a program must meet two criteria before it
+can justifiably be called \TeX: (1)~The person who wrote it must be
+happy with the way it works at his or her installation; and (2)~the
+program must produce the correct results from \.{TRIP.TEX}.
+
+\TeX\ is in the public domain, and its algorithms are published;
+I've done this since I do not want to discourage its use by placing
+proprietary restrictions on the software. However, I don't want
+faulty imitations to masquerade as \TeX\ processors, since users
+want \TeX\ to produce identical results on different machines.
+Hence I am planning to do whatever I can to suppress any systems that
+call themselves \TeX\ without meeting conditions (1) and~(2).
+I have copyrighted the programs so that I have some chance to forbid
+unauthorized copies; I explicitly authorize copying of correct
+\TeX\ implementations, and not of incorrect ones!
+
+The remainder of this report consists of appendices, whose contents ought
+to be described briefly here:
+
+Appendix A explains in detail how to carry out a test of \TeX, given
+a tape that contains copies of the other appendices.
+
+Appendix B is \.{TRIP.TEX}, the fiendish test file that has already
+been mentioned. People who think that they understand \TeX\ are challenged
+to see if they know what \TeX\ is supposed to do with this file.
+People who know only a little about \TeX\ might still find it
+interesting to study Appendix~B, just to get some insights into the
+methodology advocated here.
+
+Appendix C is \.{TRIP.PL}, the property-list description of a
+special font called \.{trip}. This is the only font used by \.{TRIP.TEX}.
+There are no graphic characters associated with \.{trip} that could
+possibly be printed; indeed, \.{TRIP.PL} describes the properties of a font
+that is as weird as the ``document'' described by \.{TRIP.TEX}.
+
+Appendix D is \.{TRIPIN.LOG}, a correct transcript file \.{TRIP.LOG}
+that results if \.{INITEX} is applied to \.{TRIP.TEX}. (\.{INITEX} is
+the name of a version of \TeX\ that does certain initializations;
+this run of \.{INITEX} also creates a binary format file called \.{TRIP.FMT}.)
+
+Appendix E is a correct transcript file \.{TRIP.LOG} that results if
+\.{INITEX} or any other version of \TeX\ is applied to \.{TRIP.TEX}
+with format \.{TRIP.FMT}.
+
+Appendix F is \.{TRIP.TYP}, the symbolic version of a correct output
+file \.{TRIP.DVI} that was produced at the same time as the \.{TRIP.LOG}
+file of Appendix~E.
+
+Appendix G is \.{TRIPOS.TEX}, a short file written out and read in
+by \TeX\ when it processes \.{TRIP.TEX}.
+
+Appendix H is \.{TRIP.FOT}, an abbreviated version of Appendix E that
+appears on the user's terminal during the run that produces \.{TRIP.LOG}
+and \.{TRIP.DVI}.
+
+The debugging of \TeX\ and the testing of the adequacy of \.{TRIP.TEX}
+could not have been done nearly as well as reported here except for
+the magnificent software support provided by my colleague David R. Fuchs.
+In particular, he extended our local Pascal compiler so that
+frequency counting and a number of other important features were added
+to its online debugging abilities.
+
+The method of testing advocated here has one chief difficulty that deserves
+comment: I had to verify by hand that \TeX\ did the right things
+to \.{TRIP.TEX}. This took many hours, and perhaps I have missed
+something (as I did in 1960); I must confess that I have not checked
+every single number in Appendices E and~F. However, I'm willing to pay
+\$327.68 to the first finder of any remaining bug in \TeX, and I will
+be surprised if that bug doesn't show up also in Appendix~E. (I plan to
+write a technical report about all of the errors ultimately found in \TeX; that
+report will tell whether any bugs are discovered between now and~then!)
+
+\vfill\eject
+
+\section Appendix A: How to test \TeX.
+
+\item{0.} Let's assume that you have a tape containing \.{TRIP.TEX},
+\.{TRIP.PL}, \.{TRIPIN.LOG}, \.{TRIP.LOG}, \.{TRIP.TYP}, and \.{TRIP.FOT},
+as in Appendices B, C, D, E, F, and~G. Furthermore, let's suppose that you
+have a working \.{WEB} system, and that you have working programs \.{TFtoPL},
+\.{PLtoTF}, \.{DVItype}, as described in the \TeX ware report.
+
+\item{1.} Use \.{PLtoTF} to convert \.{TRIP.PL} into \.{TRIP.TFM}.
+Then use \.{TFtoPL} to convert \.{TRIP.TFM} into \.{TMP.PL}. Check that
+\.{TMP.PL} is identical to \.{TRIP.PL} (this is a partial test of \.{PLtoTF}
+and \.{TFtoPL}). Install \.{TRIP.TFM} in the standard file area for
+\TeX\ font metric files.
+
+\item{2.} Prepare a special version of \.{INITEX}. (This means that your \.{WEB}
+change file should have {\bf init} and {\bf tini} defined to be null.)
+The {\bf stat} and {\bf tats} macros should also be null, so that
+statistics are kept and other special features are enabled.  Set
+\\{mem\_min} and \\{mem\_bot} equal to~1, and set \\{mem\_top} and
+\\{mem\_max} equal to~3000, for purposes of this test version.  Also set
+$\\{error\_line}=64$, $\\{half\_error\_line}=32$, and
+$\\{max\_print\_line}=72$; these parameters affect many of the lines of
+the test output, so your job will be much easier if you use the same
+settings that were used to produce Appendix~E. You probably should also
+use the ``normal'' settings of other parameters found in \.{TEX.WEB}
+(e.g., $\\{stack\_size}=200$, $\\{font\_max}=75$, etc.), since these show
+up in a few lines of the test output. Your test version should not
+change the default definition of unprintable characters (\S49 of the program).
+
+\item{3.} Run the \.{INITEX} prepared in step 2. In response to the first
+`\.{**}' prompt, type carriage return (thus getting another `\.{**}').
+Then type `\.{\char`\\input trip}'. You should get an output that matches
+the file \.{TRIPIN.LOG} (Appendix~D). Don't be alarmed by the error
+messages that you see, unless they are different from those in Appendix~D.
+
+\def\sp{{\char'40}}
+\item{4.} Run \.{INITEX} again. This time type `\.{\sp\&trip\sp\sp trip\sp}'.
+(The spaces in this input help to check certain parts of \TeX\ that
+aren't otherwise used.) You should get outputs \.{TRIP.LOG}, \.{TRIP.DVI},
+and \.{TRIPOS.TEX}; there will also be an empty file \.{8TERMINAL.TEX}.
+Furthermore, your terminal should receive output that matches \.{TRIP.FOT}
+(Appendix~H). During the middle part of this test, however, the terminal
+will not be getting output, because \.{\char'134batchmode} is being
+tested; don't worry if nothing seems to be happening for a while---nothing
+is supposed to.
+
+\item{5.} Compare the \.{TRIP.LOG} file from step 4 with the ``master''
+\.{TRIP.LOG} file of step~0. (Let's hope you put that master file in a
+safe place so that it wouldn't be clobbered.) There should be perfect
+agreement between these files except in the following respects:
+
+\itemitem{a)} The dates and possibly the file names will
+naturally be different.
+
+\itemitem{b)} Glue settings in the displays of \TeX\ boxes are subject
+to system-dependent rounding, so slight deviations are permissible. However,
+such deviations apply only to the `\.{glue set}' values that appear at the
+end of an \.{\char'134hbox} or \.{\char'134vbox} line;
+all other numbers should agree exactly, since they are computed with
+integer arithmetic in a prescribed system-independent manner.
+
+\itemitem{c)} The amount of space in kerns that are marked ``for accent''
+are, similarly, subject to system-dependent rounding.
+
+\itemitem{d)} If you had different values for \\{stack\_size}, \\{buf\_size},
+etc., the corresponding capacity values will be different when they
+are printed out at the end.
+
+\itemitem{e)} Help messages may be different; indeed, the author encourages
+non-English help messages in versions of \TeX\ for people who don't
+understand English as well as some other language.
+
+\itemitem{f)} The total number and length of strings at the end may well
+be different.
+
+\itemitem{g)} If your \TeX\ uses a different memory allocation or
+packing scheme or \.{DVI} output logic, the memory usage statistics may change.
+
+\item{6.} Use \.{DVItype} to convert your file \.{TRIP.DVI} to a file
+\.{TRIP.TYP}. The following options should be set when using \.{DVItype}:
+$$\vbox{\halign{#\hfil&\hfil#\cr
+Output level = 2\cr
+Starting page = \.{*.*.*.*.*.*.*.*.*.*}\hskip-20pt\cr
+Number of pages = 1000000&(this is the default)\cr
+Resolution = 7227/100&(this is one point per pixel)\cr
+New magnification = 0&(this is the default)\cr}}$$
+The resulting file should agree with the master \.{TRIP.TYP} file of step~0,
+except that some of the values might be a little off due to floating-point
+rounding discrepancies. Furthermore there may be differences between
+`\\{right}' and `\\w' and `\\x' commands, and between `\\{down}' and `\\y'
+and `\\z'; the key thing is that all characters and rules and \\{xxx}'s should
+be in almost the same positions as specified in Appendix~F.
+(If your \.{DVI}-writing routines differ substantially from those in
+\.{TEX.WEB}, you may want to write a \.{DVIcompare} program that
+detects any substantive differences between two given \.{DVI} files. Such
+a routine would be of general use besides.
+On the other hand, if you have set \\{dvi\_buf\_size} to 800, then your
+\.{DVI} file should be virtually identical to the one supplied.)
+
+\item{7.} You might also wish to test \.{TRIP} with other versions of
+\TeX\ (i.e., \.{VIRTEX} or a production version with other fonts and
+macros preloaded). It should work unless \TeX's primitives have been
+redefined. However, this step isn't essential, since all the code of
+\.{VIRTEX} appears in \.{INITEX}; you probably won't catch any more errors
+this way, unless they would already become obvious from normal use of
+the~system.
+
