Fortran considerations

Unlike the behavior of VS FORTRAN Version 2, where any abnormal termination is indicated with message AFB240 followed by an abend with user completion code 240, Language Environment treats an abend as a condition. The condition that represents an abend is the severity 3 condition with the message number 3250, which contains the system or user completion code and the reason code.

If this condition is not handled and the ABTERMENC(RETCODE) runtime option is in effect, then the enclave terminates with a return code of 3000 under MVS™. When the ABTERMENC(ABEND) runtime option is in effect and Language Environment terminates the enclave because of an unhandled condition, an abend occurs.
