I get the following error message when I run code from the SAS Sample Library.  I am using SAS On Demand for Academics and trying to execute the PM PROC.   WARNING: There is a problem opening the DISPLAY. The NODISPLAY option is turned on.   I don't see any option to turn display on or off.   I have double checked the example code and when it runs it is supposed to open a Display showing a Gantt Chart.   Any help would be appreciated.     data software;    input Descrpt  $char20.          Duration 23-24          Activity $ 27-34          Succesr1 $ 37-44          Succesr2 $ 47-54;    datalines; Initial Testing       20  TESTING   RECODE Prel.
