Figure 1. IOERR Format
IOERR specifies IOERR=ABE to receive user abend 999 if an I/O error should occur. This abend will cause the job step to terminate, producing a diagnostic dump.
NOIOERR is the program default. If this option is in effect, MFX will, in the event of an I/O error, terminate with either a return code of 16 or a user abend 16, depending on the RC16 option that is used.
Specify IOERR=NOSNAP to receive a user abend 999 if an I/O error should occur. This abend will cause the step to terminate, but no diagnostic dump will be produced, unless the DEBUG option is in effect.
