I guess my question is whether these tools could possibly be used in an
CPF/OS/400 commands, something like:

OVRSIOF STDIO(*IN) +
        OPNID(x) +
        TOFILE(file) +
        TOMBR(mbr) +
        TOFLD(fld (*varchar)) +
        ACCESS(*SEQ/*KEYED/*SRC/*MSGQ?/*DTAQ?/*API/etc...)

DLTOVRSIO OPNID(x) (which would actually do the processing of a previous OVR
to STDOUT).

??

Or is OS/400 not capable of something like this...?
