NOTE: SYSTASK Is Great, If You're Allowed To Use It! (XCMD)

In my previous posting I featured the SYSTASK statement as a great means of executing operating system commands in parallel. Statements such as SYSTASK and CALL SYSTEM allow any operating system command to be executed and so they can be dangerous in the wrong hands. Paul Homes recently wrote an excellent blog post about the whole subject of issuing operating system commands from SAS and the restrictions that can be placed upon doing so. Recommended.
