AIPS HELP file for OUT2CLAS in 31DEC20
As of Tue Jul 7 2:44:47 2020
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. OUT2CLAS is used to specify
the "class" field for the secondary output data file from a verb
or task. This adverb is handled by AIPS tasks and verbs under
special "wildcard" rules. These rules determine how the default
output class is combined with the user-specified OUTCLASS to
create the class field actually used. Except for '*', '?', and
trailing blanks (when an * is present), all characters specified
in OUT2CLAS are copied to the corresponding character positions in
the final class field. A '?' in OUT2CLAS causes the corresponding
character in the default class to be used. An '*' in OUTCLASS
causes 0 or more characters (as many as possible) from the default
class to be used beginning at the character position of the *.
The number of characters (excluding trailing blanks) which follow
the * in the user-specified OUT2CLAS determine how many characters
may be used. For the examples, assume that the default class is
'123456'. Then, OUT2CLAS = '*' results in an actual class of
'123456'. OUT2CLAS = 'A?B*D' results is 'A2B45D' and OUT2CLAS =
'?? CAL' results in '12 CAL'.
Null value: ' '
Taken as '*' and the "default" value for OUT2CLAS is the task name
unless the Help file for the specific task or verb states
otherwise. If the first character in OUT2CLAS is a back slash
('_'), then the default is changed from the task name to the
actual INCLASS. The _ does not appear in the final output class,
but the remaining 5 letters (if any) in OUT2CLAS are used as above
(as if they had been typed in character positions 1 - 5 of
