Subject: L3 server versions
Doesn't look like it. No OSWORD 14 or 15 calls either. The code to 1.06 uses
OSBYTE 150 and 151 to read the clock. These are also not present in the
code. The only other two things I can think of are:
1) that it was a "working version" and not released, but then why would they
take out the code and force themselves to enter the date and time each time
they ran it. Plus they would have had easy access to a clock.
2) they were getting pushed for space. The working space start in 1.07 has
already been moved from &8B00 in 1.06 to &8C00 finishing at &F7FF.
Any other ideas?
