+From: Barbara Beeton
+
+Subject: more errata; corrections to TEX82.BUG and CM changes
+
+
+Don Knuth says
+
+ people still read those books
+ and still find mistakes! 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.)
