View source for Emulator configured for 27x132

It's easy to check to see if a user's session is configured to support 27x132 columns.  Below is an example program that checks to see if a user's session supports 27x132.  

In your 27x132 program, make the display file USROPN. Then prior to opening the display file, call the below program.  If the answer comes back 'N', exit the 27x132 program.
