Could be.  I understand your point, but this is a practice (a good one)
rather than a stated requirement that I'm aware of.  Maybe it's even a
strong suggestion.  Yes, defining it in WS will (OK, *SHOULD*) protect you
from this particular anomoly, but what guarantee do we have of that?

If in fact the compiler can choose to clear fields outside of documented
means (and again, if this is documented, then show me where and I'll be
less disgruntled).... what reliability do we have in any area, including
WORKING-STORAGE?

Dennis.

May be this is why it  has been 'normal' in COBOL environments to have a
WORKING-STORAGE area to work on before you write or modify  a record.
Working directly on the file buffer has not been 'good latin'.

If you define your record in Working-Storage and use WRITE record FROM
WS-RECORD-DEFINITION, you will avoid the problem. The contents of
WS-RECORD-DEFINITION will not be affected when you write the record..
