\ctrline{\:D WEB version 0.9 Errata}
\vfill
Version 0.9 is bedevil with more than it share of errors. Most of these
are fairly trivial and will be obvious to the reader
but here are two changes that should be noted:
\vfill
Module 67 of WEAVE has been modified and should read:
\M67. Procedure \\{prime\_the\_change\_buffer} sets \\{change\_buffer} in
preparation
for the next matching operation. Since blank lines in the change file are
not used for matching, we have $\\{change\_limit}=0$ if and only if the
change file is exhausted.

not used for matching, We have $\\{change\_limit}=0$ if and only if the

β{yVλ1:z actuAlhp∩A!CmJA¬\AMh31 has a table with a few cases of items in the left column
that crash into items in the right column.
5) The 'prime the change buffer' procedure should be changed to skip over
lines containing only spaces, rather than just skipping lines with
no characters at all (since some systems don't support variable
length lines).
6) Appendix F is missing material. This appendix is in process of change
for \TEX 82. The version on tape is correct for the present.
7) Page 58 is smeared.
8) The index to WEAVE should include things like "\X", "\C", etc.
