[comp.sys.atari.st] Repost of link68 fix

sansom@trwrb.UUCP (03/04/87)

I finally got a chance to dig this thing out of my archives.  It was posted
quite some time ago (a year?) and contains a fix to the pathname problem with
link68, the Alcyon/DRI overlay linker which comes with the developer's kit.

p.s. - this thing _does_ work, however there still seems to be a problem
with long pathnames.  I don't remember the exact length which works, but I
think it's somewhere around 13-14 characters.

Trying to overcome the problem with LINK68 not accepting pathnames I found
a scanner control table starting at file-offset 0x8144.
The command scanner of LINK68 uses a byte entry of this table indexed by an
input character as a control pattern specifying the character class.

The backslash entry at file-offset 0x81A0 has the value 0x02 which is a
separator pattern.
Patching it to value 0x04 puts the backslash into the number class.
After this fix LINK68 treats the backslash as a normal identifier character
but GEMDOS still sees a pathname.
