...; however, remember that PQL_MBYTLM over-rides PQL_DBYTLM and the UAF
record parameter BYTLM, unless, as suggested, the $CREPRC uses an
explicit value for that parameter, in which case eitherthe source for
the program will have to be checked/changed, or the parameters it uses
will.

Hard-coding such a value would earn one a major smack, in my estimation.
