HELP SECTION

IN3CLASS
Type: Adverb  (String*6)
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.
      IN3CLASS is used to specify the "class" field for the 3rd
      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
      IN3CLASS must exactly match the corresponding characters
      in the test string.  A '?' in IN3CLASS matches any single
      character in the test string.  An '*' in IN3CLASS matches
      0 or more characters in the test string.  Thus, IN3CLASS
      = '*' matches any test string.  IN3CLASS = '??B*D' matches
      'ASBD', 'XYBXDD', and 'A3B45D', but does not match 'ABCD',
       'BCD', or 'XYBXDE'.
Null value:  '      '
      Taken as '*' unless the Help file for the specific task
      or verb states otherwise.
