The SAS display manager is a comamnd line interface to the SAS system, which remains in Base SAS as a legacy facility.
However the online documentation on how to use this facility is sparse at best, and google searches are less than fruitful.
A common DM command would be: CLEAR LOG; CLEAR OUTPUT; WPGM;
My question is - What other DM commands are out there?
Here are some links that have a large number of commands:
FSP Commands
Commands specific to Windows
AF Windowing Commands
Commands for the Program Editor (Scroll down to second paragraph)
