AIPS HELP file for OUTSEQ in 31DEC20
As of Mon Sep 21 9:36:38 2020
Type: Adverb (Real)
Use: Data files are stored in AIPS under logical names which
have 3 parts: a 12-character "name" field, a 6-character
"class" field, and a numeric "sequence number" field.
OUTSEQ is used to specify the "sequence number" field for
the output data file from a verb or task. It is used as
an integer number between -1 and 9999.
Null values: 0 and -1
-1 means to use the same sequence number as that found
for the first input image (actual INSEQ with null value
filled in). 0 means find the image having the highest
sequence number which is consistent with the other output
name adverb parameters and use a sequence number 1 higher.
If there is no such image, then use OUTSEQ of 1. The
phrase "0 => highest unique", used a lot in Help files, is
intended to be a code for this standard default behavior.
