If neither the NOW nor the FINISH option is specified, NOW is taken as the
default. If neither the KEEP nor the NOKEEP option is specified, KEEP is
taken as the default. If the OFFSET option is not specified, the spooler
retains the present location in the output spool file. This is the default.
The combination of the NOW, KEEP, and no OFFSET parameters (all
defaults) is a special case. When an active spooler receives this form of the
SUSPEND option, it suspends after processing the current record. A
subsequent SPOOLER...; RESUME with no OFFSET parameter and without
an intervening SPOOLER...;RELEASE causes the spooler to resume at the
next record, as if it had never been interrupted.
If a spooler process is suspended in the middle of a spool file and the file is
not retained by the spooler, a page number is saved in the spool file's file
label extension (FLABX). This page number is either the last complete
page that was printed (if no OFFSET was specified) or one page prior to that
specified by the final OFFSET applied to the file (with a lower limit of 0).
The next time the file is selected for printing by any spooler, output
resumes at the page following the page saved in the FLABX.
NOTE Because of the large amount of data buffered in the file system and the
device, the device may continue to print, making it appear as if the SUSPEND
parameter has not had any effect. In reality, the spooler stops sending data to
the device when the command is received but must wait until all buffered
data has been printed before suspending. Depending on both the content of
the data and the amount of buffering, this may require a significant part of a
page or even several pages.
The spooler process notifies you via the following message that it has processed the
command:
IOutput spooler, LDEV ldev :

If a spooler process is suspended in the middle of a spool file and the file is
not retained by the spooler, a page number is saved in the spool file's file
label extension (FLABX). This page number is either the last complete
page that was printed (if no OFFSET was specified) or one page prior to that
specified by the final OFFSET applied to the file (with a lower limit of 0).
The next time the file is selected for printing by any spooler, output
resumes at the page following the page saved in the FLABX.
RESUME The RESUME option resumes a suspended spooler process and is therefore
valid only for output spoolers. The spooler must be in the SUSPEND state. If
the spooler retains a spool file when it is suspended (meaning the KEEP
option was specified or taken by default), and the spool file is not
subsequently released, the OFFSET option is valid. If no offset is specified
with either the earlier SUSPEND or the present RESUME, then output
resumes where it left off. If an OFFSET is specified at either time (or both),
the spooler resumes at the final location indicated by the offsets. If OFFSET
