Type: Adverb (Real)
Use: Data files are stored in AIPS under logical names which
have 4 parts: a 12-character "name" field, a 6-character
"class" field, and a numeric "sequence number" field.
IN4SEQ is used to specify the "sequence number" field for
the 4th of the input data files used by a verb or task.
It is used as an integer number between 0 and 9999.
Null value: 0
Null value means take the image having the highest
sequence number which is consistent with the other adverb
name parameters unless explicitly stated otherwise in the
Help file for the verb or task.
