SPFON
SPFON is a basic panel command that you can issue from any product panel. It enables the use of ISPF as the dialog display mechanism when it has been temporarily disabled using the SPFOFF command. This value remains in effect until you either change it or end your product session.
This command is ignored if it is issued from a session running under native TSO.
