Valid values are TRUE and FALSE. Only "=" and "<>" are allowed as relational
operators. This attribute does not apply to input spool files; therefore, any logical
condition involving the attribute always returns FALSE when tested against an input
spool file.
•
parm ::= DATE: Creation date in the format mm/dd/yy or mm/dd/year . Note that the
year can be in the form of
yy , as in 10/10/88, or in the form of year , as in 10/10/1988;
both are legal syntax for the
date parameter.
indirect_file Specifies the name of a file containing the selection equation. It must be
preceded by a caret (^). The selection equation contained in the file may
not exceed 509 characters in length, including the brackets in which it
must reside. There is no restriction on the indirect file code. If the record
size exceeds 509, only 509 characters per record are read and a warning is
issued. Backreferencing to a formal file designator is also allowed for an
indirect_file name; that is, ^* filename is also allowed. Any file is
accepted as an
indirect_file , unless the file system returns an error
from FOPEN or FREAD.
There is no limit to the number of records in the
indirect_file , only the
total character count.
Records are processed as follows:
• Leading and trailing blanks are stripped.
• If the last non-blank character is an ampersand (&), it is also stripped;
otherwise, one blank is added back to the end of the record as a
delimiter.
• The character count of the record is added to that of the records
processed previously. If the total character count exceeds 509, an error
is returned. If the total is less than 509, the current record is appended
to previous records.
• This process repeats until either 509 characters have been counted or
the end-of-file is detected. Records terminating with or without
ampersands may be mixed as desired in the indirect file.
• If the resulting string is ≤509 characters, it is parsed.
• If the parser detects a syntax error, or if any non-blank character
follows the closing bracket (]) of the
select-eq , an error is returned
and the
select-eq is not processed.
ALTER The ALTER option alters the characteristics of specified output spool files.
Private output spool files may be altered in a limited fashion; only the
keywords PRI, DEFER, and UNDEFER are allowed. A system manager (SM)
user may also specify DEV=.
NOTE You cannot alter the attributes of spool files in the SPSAVE state.
If you use the DEFER or DEV keyword on a spool file that is being printed, the spooler
process printing the file is interrupted. The spooler process saves the page number of the
