HELP SECTION
IN2NAME
Type: Adverb (String*12)
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. IN2NAME is used to specify
the "name" field for the 2nd of the input data files used by a
verb or task. This adverb is handled by AIPS tasks and verbs
under special "wildcard" rules. These rules determine which test
strings (e.g. image names in the catalog) match the user-specified
string. Except for '*', '?', and trailing blanks (when an * is
present), all characters specified in IN2NAME must exactly match
the corresponding characters in the test string. A '?' in IN2NAME
matches any single character in the test string. An '*' in
IN2NAME matches 0 or more characters in the test string. Thus,
IN2NAME = '*' matches any test string. IN2NAME = 'A?B*D' matches
'ASBD', 'A BXYZD D', and 'A3B45678901D', but does not match 'ABCD'
or 'ASBCDE'.
Null value: ' '
Taken as '*' unless the Help file for the specific task or verb
states otherwise.
