Message compiler return codes

The message compiler generates a return code contained in register 15 and compiler error messages, both of which can be sent to SYSPRINT. The return codes are as follows:

Code	Meaning
0	Successful completion
4	Process complete. Run-time message file is complete but the compiler generated warnings.
8	Processing complete. The run-time message file is usable but incomplete.
12	Processing ended prematurely. The run-time message file is unusable.
