The Change Cancel Key  command works in conjunction with  the RTVCNLKEY
tool  command.   CHGCNLKEY allows the  setting of  the Cancel  and Exit
key  information  which may  be of  value when  mixing system  and user
functions.  The QWCCCJOB API is used.

A typical command would be:

              CHGCNLKEY   CANCELKEY(*OFF) EXITKEY(*OFF)

At the  conclusion of  the command, the  use of  the RTVCNLKEY  command
would return both values as *NO.

The  Cancel and  Exit keys  are set  by many  system functions  such as
entering  an interactive command, using a  system display command, etc.
Using commands within  a CL program  that do not  cause a display  does
not change the settings.
