External Call Error Processing

If the RETURN line for the external call table has CLASS=STATUS, the GT.M run-time system reports an unsuccessful status (an even number) with the message:

	GTM-E-ZCSTATUS, External Call: Unsuccessful return status
	

If a run-time error occurs within the external routine, GT.M issues the run-time error message:

	GTM-E-ZCUSRRTN, External Call: Run-time error in user routine
	

For an explanation of error handling, refer to the "Error Processing" chapter in this manual.
