1... .... RECOLDTQ X'80' RECOLDTQ RECTQUE flag is
not current (i.e. it has the
message number of an RSSBK that
has not been retrieved from the
checkpoint area yet.) NOTES : The
following field is used to
indicate when the RECBK format
has changed and what that change
was due to. Any code defined here
should be checked in HCPRECKP
when old format RECBKs are read
from the checkpoint cylinders.
The old format RECBKs should then
be updated appropriately to the
new format. Code should also be
added to HCPRIUCF and HCPRECRI to
set the code for any RECBKs that
are being newly created AFTER the
format change. A new code should
only need to be defined here when
a change to the RECBK causes it
to be incompatible with a
previous format (as in the case
of the RECTCNT field being
expanded from a halfword to a
fullword). Due to compatibility,
the displacement of this field
should NEVER change. Previous
versions of this control block
had this field marked 'RESERVED'
and the field was known to be
zero. Therefore, previous
versions were version X'00'.
