You can use the callable interface to use any QMF command that you would use in a procedure. However, there are three commands that have special syntax for the callable interface:
START works only in the callable interface. To use GET GLOBAL and SET GLOBAL in a callable interface application written in a language other than REXX, use the extended syntax. The extended syntax of the SET GLOBAL command allows you to set global variables that have values up to 32 768 characters long. For more information on using the GET GLOBAL and SET GLOBAL commands in an application, see GET GLOBAL and SET GLOBAL: Extended syntax.
For information about these and other commands you can use in a callable interface application, see QMF Commands in Applications. To see examples of the START and SET GLOBAL commands for each language, see the sample program for each language:
