SPAWN=WAIT | NOWAIT

WAIT

causes SAS to assume that the terminal can be used to take input from the user. This is the default.

NOWAIT

causes SAS to assume that the terminal cannot be used to take input from the user. Therefore, SAS will not run in interactive line mode. Attention handling is disabled. However, you can run SAS in batch mode or in the Motif environment. The following is an example of using this option:

$ SPAWN/NOWAIT SAS/SPAWN=NOWAIT MYFILE.SAS

Specifying SPAWN=NOWAIT in this situation is highly recommended. If you do not specify it, unnecessary interactions occur between the spawned SAS session and your terminal.

Details

The SPAWN= system option facilitates smooth operation of SAS in a SPAWN/NOWAIT subprocess.

To terminate the subprocess that runs SAS, use the DCL STOP command.
