What it does

This SAS Macro opens a Program Editor Window in the SAS Display Manager and loads the file specified by parameters xpath and xentry.

  • When xpath is not supplied, the macro XSET is called to get the user's home directory and then uses this path.
  • When xentry is not given, the macro calls XDIR to list the directory content in the LOG screen.
