Although my program is written in Pascal, this really isn't a Pascal
problem but an AIF problem/issue.
My call to AIFPROCGET is returning a positive value in the overall status
field because it doesn't like item 2063 (return a table of file numbers
of files being accessed by other processes:
The AIF manual states that item 2063 is not putable and not verifiable, but
does this mean it is not gettable either?
I hope someone out there can enlighten me as to why item 2063 is giving me
a problem here.
TIA,
Brian.
