I just added errata for pages A383 and C271. + Page A383 should have been updated when I made TeX version 1.3 in 1985! + +Changes to ERRATA.TEX are included below. + +A small correction has been made to TEX82.BUG in a very old change; it +affects only documentation, and corrects a module number. + + +Chris Thompson has informed me that some lines in the difference list for +SYMBOL.MF were corrupted. I believe that all of these were in the final +context lines, so anyone who has tried to apply the changes by hand has +probably been able to get a correct file. Nonetheless, the correct +difference list is given below. (The discrepancies are due to a glitch in +the software used to transfer the difference files from a DEC-20 to a +VAX/VMS. I knew this was a problem, and checked all the difference files +accordingly, or so I thought. This one slipped through somehow. Apologies.) + + +After contemplating the nature of the last two bug fixes to TeX and MF, I +have decided that a cumulative list of differences might be useful to anyone +who may have delayed installing the changes conveyed in these messages. +The following cumulative difference lists now exist, and I will be happy to +send one or more of them to anyone who sends me a specific request. + + TeX 2.0 (Dec 86) through 2.7 (Nov 87) + TeX 2.7 (Nov 87) through 2.95 (Dec 88) + MF 1.3 (Dec 86) through 1.7 (Dec 88) + + +When I communicated the changes for TANGLE 2.9 in message 11, I failed to +include Knuth's explanation. Here it is. + + At the suggestion of Wayne Sewell, who is writing a book about WEB, + I've removed a restriction: One can now use a nonnumeric macro + before declaring it. (The old documentation for section 59 of TANGLE + mentioned that this restriction wasn't really necessary. I've finally + eliminated it, because Wayne found it a hassle, and I wanted to reward + him for all his hard work. + + The only change, except to version number and documentation, is + to insert `if t=numeric then' before the first err_print in section 59. + The only change as far as users go is that some programs that used to + give error messages will now run without error. + + Programmers who use a macro before declaring it may get a spurious + warning about conflict between identifiers with the same first six letters; + TANGLE won't know that certain identifiers will later become macros. + +The changes to TANGLE precipitated some changes in the WEB manual. Those +changes are listed below. + + +In response to an inquiry for suggestions on how the TRIP and TRAP LOG files +might safely be sent across unpredictable gateways, I was sent two small C +programs, one to hexify files and the other to unhex them. Here is the +description and a warning that came with the code: + + The C programs hex.c and unhex.c translate between 8-bit binary files + and straight hex files, in which every pair of hexadecimal digits + corresponds to a single 8-bit byte. Certain files in the Kermit + distribution are in this format. You can recognize them because they + contain only the characters 0-9 and A-F -- no colons or other characters. + + Warning - HEX.C doesn't work under Microsoft C on the IBM PC family: + getchar() returns EOF (-1) whenever it reads a 0xFF byte from the input + file. Seems like a bug in MSC... Since everything is an int, there + shouldn't be any sign extension going on. Boo. Testing with feof() + wouldn't help either, because getchar() buffers ahead. Maybe use + single-character read()? + +This seems the most promising method I've heard about so far. I doubt very +much that any 0xFF bytes will occur in the LOG files, so that doesn't seem +a problem. I plan to test this out, and if I can succeed in making it work +here, the next message will include the C code, and then I will begin to +send out the long-awaited TRIP and TRAP. If anyone believes they would have +a problem with this technique, please let me know; on the other hand, if +anyone has another reasonable suggestion, I'd like to hear that too. + + +I was notified by my system administrator that at least two copies of the +last message failed to be sent, but the addresses were scrambled and there +was no way to identify the intended recipients. If you have missed any +messages, please let me know, and also acknowledge receipt of this one. +I will be out of town from Jan 13-30, and I will try, after I return, to +query anyone from whom I haven't received a reply. (TRIP and TRAP will +also have to wait until after I return, but I hope finally to be able to +take care of them quickly then.) + + +######################################################################## + +Extracts from ERRATA.TeX (differences as compared with previous version) + +;COMPARISON OF PS:<TEX.DOC>ERRATA.TEX.18 AND PS:<TEX.DOC>ERRATA.NEW.2 +;OPTIONS ARE /E /3 + +**** FILE PS:<TEX.DOC>ERRATA.TEX.18, 2-51 (2996) +\bugonpage A454, lines 23--29 (8/13/87) +**** FILE PS:<TEX.DOC>ERRATA.NEW.2, 2-51 (2996) +\bugonpage A383, lines 7--15 from the bottom (1/4/89) + +\begintt + 209 strings out of 1685 + 1659 string characters out of 17636 + 27618 words of memory out of 52821 + 1172 multiletter control sequences out of 2500 +\endtt +Consequently there was plenty of room for more macros: $52821-27618= +25203$ unused cells of main memory, $2500-1172=1328$ of name memory, +$1685-209=1476$ of string memory, and $17636-1659=15977$ of character memory. +But a fairly large \TeX\ was being used, and only the macros of +Appendices B and~E were loaded;
