However, Amy, when I run with older version of AIPS (31DEC03) with
exactly same inputs of AIPS as earlier, it gives this funny thing but runs
properly

(note that there are problems with new ADVERBS, and trying COMPRESS, or
RESTORE 0 did not help. I had to do a trick by not updating ADVERBS
list, i.e., do not run any of the above two commands in AIPS).
So, there seems to be some problem with the new one.
Thanks and regards,
Poonam.
