Invoking existing applications
To access Language Environment,
you will need to change the procedures that you use for invoking applications.
The procedures required for non-CICS applications are different than the
procedures for CICS applications.
Note: Make sure your program names do not begin with AFH, CEE, EDC, IBM, IGZ,
ILB, or FOR. These prefixes are reserved for Language Environment library
routine module names.
