IGZ0016W   Program program-name could not be deactivated by non-return exit of a routine. Subsequent reentry is not supported.

A COBOL program cannot normally be recursively entered. When non-return style procedure collapse processing is being performed for a COBOL program, an attempt is made to reset the program to a state where it can be recursively entered. This is not supported for certain combinations of function used within the program. After this message is issued, any attempt to reenter the program will result in message IGZ0015S and termination of the enclave.
