SET.TITLE (SETT)
$ For OS 2200 based LINC Systems, the file name cannot contain more than one asterisk
character, and cannot be longer than 25 characters. Each portion of the file name,
before and after the asterisk, cannot be longer than 12 characters. If no asterisk
character is used, the maximum is 12 characters.
$ For UNIX LINC Systems, the name may be any valid pathname up to 100 characters in
length. Within that, the filename may be up to 14 characters in length. If you do not
specify an absolute path name for the file, the file name is relative to the LINC System
directory.
If the Extract file is to go to TAPE, the value of this parameter depends on the host type, as
shown in the following table.
ON; data name 2
Host type Parameter value
MCP

OS 2200

Tape name
Tape serial number
UNIX Pathname to the tape drive
Note: This command option is valid only for MCP based LINC Systems.
This command option gives the disk pack name if the Extract file is to go to disk (that is,
DISK was selected on the Extract File Options screen).
EXIST;
If you include this command option, the file will be treated as an existing file, and it will
not be cleared unless the first access is by way of an EXTRACT; command.
If you do not include this command option, the standard SET.TITLE; command will
operate in the same manner as the RETAINED.AS; command option, namely:
$ If the first command after the SET.TITLE; is a SORT; or DETERMINE; ACTUAL,
(without the EXTRACTED.AS; command option), the file will be initialized (created
with no records).
$ If the first command after the SET.TITLE; is a DETERMINE; ACTUAL with the
EXTRACTED.AS; command option, the file will be treated as existing, and it will not
be cleared or initialized.
$ If the file is not used after the SET.TITLE; command, then when the Report completes,
the file will be empty.
