I have an existing COBOL application that cannot be changed, at least, let's say it can't.
The COBOL application accepts an input file of an arbitrary record length like so:
SELECT C1BMNAM
ASSIGN TO DISK-C1BMNAM
FILE STATUS C1BMNAM-FILE-STATUS
.
I want it to process the file sorted by a certain position/length (ZIP Code) determined at run time. But if I create an LF, it doesn't read it in order by key.
What I thought I could do was use OPNQRYF to do that sorting on the fly, something like:
OPNQRYF FILE((METZ3410/PF)) KEYFLD((*MAPFLD/ZIP)) MAPFLD((ZIP '%sst(pf 133 5)')) OPNID(C1BMNAM) SEQONLY(*NO) OPNSCOPE(*JOB)
That works for a file with one field. The COBOL is none-the-wiser.
But the input file might have multiple fields. All I know is the position/length.
Is there some way to make my MAPFLD substring the entire record without knowing what field the position/length actually falls into? I just want to substring the entire record.
Because the file may be very large, I do not want to take the performance hit of copying it to a single-field file. But if there were some other way to trick it...
Thanks in advance for any and all suggestions.
