[daip] SCMAP oddnessh

[Michael Bietenholz]

Our grad student, Sasha Novikov was having a wierd problem with SCMAP
(31DEC08; MNJ today) and I couldn't figure out what was wrong, below
are the messages.  The SCMAP inputs were generic (sorry, don't have
exact copy; solmo P, solty L1, solint 1min; APARM 0; NMAP 5; nothing
set for OUTNA, OUT2NA, OUTCL etc.  IMAGR with exactly the same inputs
runs fine.

SCMAP runs, puts the first image up on the TV, allows you to
manipulate clean boxes, but on the first "continue cleaning" it bombs
with the CATOPN messages below.  The "ERROR 1 COPYING CATBLK DISK, CNO
0 1" message seems odd because it shouldn't be DISK=0 (no such thing),
and it shouldn't be CNO=1 as the input, and all the output files ought
to have CNO > 1.

Other possibly pertinent info, I tried exactly same thing on 31DEC07
and it worked fine.  IBM laptop running Linux (Ubuntu?). There is
plenty of disk-space.  User has write permission on aips DATA area,
other aips task work fine, no problem with creating files, reading
them etc.

If you have an idea of what's going wrong, can you reply to
sasha at sgl.sci.yorku.ca witha copy to me (I'm on holiday for a couple
of weeks, so he'll have to try and sort it out himself).

         thanks,         michael bietenholz
