LK-KARI@FINTUVM.BITNET (Kari Sutela) (03/15/89)
Earlier this year I reported a bug in ARexx's date()-function to Bill Hawes
and he kindly replied to me and said that he is preparing a patch to the
rexx library which should correct this and some other bugs. He promised to
send this patch to comp.binaries.amiga as well as BIX. Nevertheless, this patch
hasn't showed up in here. BTW, in a recent letter he said that his usenet-
connection has dried up - this might be the cause for its non-appearance.
Now I must ask all you with a BIX-access if it has been posted there. If so,
how could I get it? Well, I could always ask Bill himself for the patch, but
I think this patch is not too improtant - if I can get it by email, I'll
be satisfied, but it's not worth sending disks across the Atlantic. Anyway,
the bugs are minor and haven't bothered me too much.

PS. If you are curious about the date()-bug, try setting the system date to
Newyear's eve (Dec 31) and checking what date() returns. Amusing, isn't it.lfk@uts.amdahl.com (Lynn Kerby) (03/27/89)

I don't know if you would have seen this, as I posted this back in November of last year. The following shar contains the source and uuencoded binary for a patch to fix the DATE() function in rexxsyslib.library. Read the README for details. Lynn Kerby ---------Cut Here------ #! /bin/sh # This is a shell archive, meaning: # 1. Remove everything above the #! /bin/sh line. # 2. Save the resulting text in a file. # 3. Execute the file with /bin/sh (not csh) to create: # README # rxpatch.c # rxpatch.uue # This archive created: Sun Mar 26 21:02:37 1989 # By: Lynn Kerby (Amdahl Corporation, Sunnyvale, CA) export PATH; PATH=/bin:/usr/bin:$PATH if test -f 'README' then echo shar: "will not over-write existing file 'README'" else cat << \SHAR_EOF > 'README' This is a small program to patch (and unpatch if desired) the rexxsyslib.library file for AREXX v1.06. It attempts to do reasonable things on error, but doesn't go as far as it probably could. If you are not running v1.06, do not try running the patch program!! The problem is that the new DATE() function doesn't understand that people like to see dates like 31-jul-88 instead of 00-aug-88. I called Bill Hawes and he said the change was pretty minor, so I decided to try finding the code in rexxsyslib.library that needed replacing. If you don't feel like trusting my code, the change is pretty easy to make using a filezap utility. OFFSET 0x7c88 VER 0xb44064ee REPL 0xb44062ee (Using NewZAP, the mod goes at offset 0x88 in sector 63 of the file) The program makes it a little easier. Syntax is rxpatch [-r]. The -r option will remove the patch if you want to get rid of it. You will have to kill the Master Rexx process (via. rxc) and flush the libraries for this to take effect. Running rexxmast again will cause the library to be read in from disk with the patch. All standard disclaimers apply, and please keep a copy of the old rexxsyslib.library around in case something goes wrong!
