Re: Dual Format

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

I understand the concept, and this is what I wanted to do, I am
just not sure how to implement it.

My file definitions for my DDS will have the various record layouts
externally described.  Then I can use this DDS, my concern is, how
do I get the buffer I have just written to single field for the actual
physical file itself?

For example, my header record has 7 fields, UCACCT, UCBRCH,
UCCCNT, UCDATE, UCAMNT, UCFILL and UCCODE.

My physical file will have one field, maybe I'll call it UBBUFF.

I can't say MOVEL UBCntrol01   UBBUFF  can I?
UBCntrol01 being my record format name for the header DDS.

Do I have to create a Data structure listing all my fields in my
program?  If so, it would be just as easy to internally describe
the file then.  I don't want to have to list the fields in my program.

Regards,

Jim Langston
