Command Definitions SP-Z
SPOOLER
Either a STOP or SUSPEND that includes the FINISH option may be
accelerated to a higher-priority command without waiting for the present
spool file to finish printing. For example, SPOOLER...; SUSPEND;
FINISH may be followed by:
SPOOLER...;SUSPEND;NOW
or
SPOOLER...;STOP;FINISH
or
SPOOLER...;STOP;NOW
Similarly, a SPOOLER...;STOP;FINISH may be accelerated to
SPOOLER...;STOP;NOW. To go in the opposite direction is an error.
NOW Directs the spooler to immediately stop the current output. This option
may be used only in conjunction with the SUSPEND or STOP options. If it is
used in any other context, a warning is issued. This is the default.
If NOW is used on the SUSPEND option with either the NOKEEP or OFFSET
parameters, the spooler prints a trailer if required; otherwise output
pauses and may be resumed later at the point of suspension.
The NOW option is not valid for spooled input devices.
KEEP Directs the device to retain ownership of the spool file that it is currently
processing. This is the default. KEEP is valid only if all three of the
following conditions are satisfied:
• KEEP is used as a parameter to the SUSPEND option or, it is taken as the
default.
• The spooler is actively processing a file or is suspending.
• The NOW parameter is also specified or taken by default.
If the OFFSET parameter is not specified (or this condition is taken by
default), the spooler suspends after processing the current record.
NOKEEP Directs the spooler to close the spool file that it is currently processing.
NOKEEP is valid only if all three of the following conditions are satisfied:
• NOKEEP is used as a parameter to the SUSPEND option.
• The spooler is actively processing a file or is suspending.
• The NOW parameter is also specified or taken by default.
The spooler stops sending data after the current record, ejects a page,
processes any specified OFFSET, saves the result of that processing (or the
last completely printed page if no OFFSET was specified) in the FLABX
(file label extension), prints a trailer with (INCOMPLETE) on it if trailers
are enabled, and returns the file to the READY state. The next spooler that
