This command is only applicable under CICS.
%QO
|
In a Natural session running under CICS in pseudo-conversational mode,
you can switch to another CICS transaction by issuing the statement CALL
'CMTASK'
. To enable CICS to start the other transaction, a terminal I/O,
i.e. an INPUT
statement, is required after the CALL
statement.
To suppress the screen output of that INPUT
statement
(which would be overwritten immediately by the started transaction anyway), you
issue a SET CONTROL
'QO'
statement before the INPUT
statement.
