You could also look into using SYSTASK.
Executes, lists, or terminates asynchronous tasks
SYSTASK COMMAND "operating system-command"
<WAIT | NOWAIT>
SYSTASK LIST <_ALL_ | taskname> <STATE> <STATVAR>;
SYSTASK KILL taskname <taskname...>;
SYSTASK allows you to execute operating system-specific commands from
within your SAS session or application. Unlike the X statement,
SYSTASK runs these commands as asynchronous tasks, which means that
these tasks execute independently of all other tasks that are
currently running. Asynchronous tasks run in the background, so you
can perform additional tasks while the asynchronous task is still
For example, to copy a SAS program, you might use this statement:
systask command "copy myprog.sas myprog1.sas"
The return code from the copy command is saved in the macro variable COPYSTAT.
That was all from the online doc. I have SYSTASK in the past on UNIX
but have not used it in the past 2 years or so that I have been
running SAS on a windows program server.
That said I could envision a SAS program that starts other SAS
programs using SYSTASK waits for them to finish examines return codes
or other expected output and starts other SAS programs depending on
the results of those returned objects.
