Running code in the Display Manager can leave of residue other than data in
the WORK library and text in the Log and Listing windows. For example, there
can be changes in system options and macro variables in the global symbol
table. To be sure that you have a "clean" environment for each task, restart
SAS Display Manager or run code in batch.
