Bruce, you miss my point.  With this code:

       01  DSPFILE-area.
           copy dds-m1map-o     of OE314D.
           copy dds-m2ctl-o     of OE314D.
           copy dds-m2sfl-o     of OE314D.
           copy dds-m2key-o     of OE314D.

The four data structures OVERLAP.  Changing a field in dds-m1map-o will ALSO
affect all three other formats.  And it's unlikely that those changes are
ones you want.  With this technique, I can't just initialize a field in
dds-m2ctl-o and be assured it will stay that way throughout the life of the
program.

I understand all about MOVE CORR and the joy it brings.  I use it
extensively in my COBOL version of PSC/400.  But I ran into difficulties
with the above coding technique.
