SETWID USER'S GUIDE  --  JWB -- 1982-APR-15 -- REVISION 0

Purpose:  Set a VT100 terminal to 80 or 132 column mode.

Usage:    CALL SETWID(80)
          CALL SETWID(132)

          Note:  If you are using a dial-up line, you must first
          issue the DCL comand:  $SET TERMINAL/VT100
          so the system will know what kind of terminal you are using.

          This subroutine checks the terminal type, and returns
          without doing anything if the terminal is not a VT100.
