The OUTPUT statement must precede any COMPUTE statement that references O-type output items.
When running in z/OS or VM, do not code DCB information for output files (unless you are writing to a member of a partitioned data set), as this is provided by CA JARS Wizard.
If the OUTPUT glossary name is FILE or CARDS, the RECFM parameter is limited to F or FB. V, VB or VBS are reserved for use by CA-developed glossary names.
