The
SPAWN= system option enables you to run the SAS System in a SPAWN/NOWAIT subprocess.
This method of running SAS is similar to batch mode if you do not specify /DMS or /EXPLORER. The
only difference is that in batch mode, SAS runs in its own process rather
than in a spawned subprocess.
When you specify SPAWN=NOWAIT in
the SAS command and do not specify /DMS or /EXPLORER, the
SAS System assumes the terminal cannot be used to take input from the user.
Therefore, the SAS System will not run in interactive line mode or in the
windowing environment using the terminal-based windowing environment if you
do not specify /DMS or /EXPLORER. You
can, however, run the SAS System in batch mode, or invoke SAS under the Motif interface,
as shown in the following SAS commands:
$ SPAWN/NOWAIT SAS7/SPAWN=NOWAIT MYFILE.SAS
$ SPAWN/NOWAIT SAS7/SPAWN=NOWAIT/EXPLORER
$ SPAWN/NOWAIT SAS7/SPAWN=NOWAIT/DMS
Attention-handling is disabled
if you are running the SAS System with SPAWN=NOWAIT in
effect. Thus, to terminate the subprocess running the SAS System, use the
STOP DCL command.
For details about invoking the SPAWN= system option,
see SPAWN=.
