Using the Correct Calling Convention

To run the RM/COBOL library routines provided in Studio Enterprise Edition, you set the DIALECT(RM) Compiler directive, which sets the required calling convention. To run the Studio Enterprise Edition library routines, you use the standard COBOL calling convention.

If you have RM/COBOL compatible library routines and Studio Enterprise Edition library routines in the same program, do one of the following:

• Set the DIALECT(RM) Compiler directive to enable the RM/COBOL library routines, then explicitly use the standard COBOL calling convention for the Studio Enterprise Edition library routines.
• Explicitly use the 1024 calling convention for calls to the RM/COBOL compatible library routines if DIALECT(RM) is not set.
