Um, wouldn't

02  main-key.
  03  primary-number pic x(5).
  03  sub-number pic x(5).

Have been more effecient? Here main-key is still, logicall, x(10), and can
be accessed as such. You don't need sub-area, so removing both you also
get rid of the redefines. For this particular definition they don't appear
to be necessary.
