5.1.4.3 VCCQSCAN--Common Parameter Queue Scan Routine

VCCQSCAN is a common routine that scans lists of values that
VCCPARSE creates when it encounters KEYWORD=(list)
parameters.  VCCQSCAN is passed:

    o  The address of the list (all lists are chained from
       the common work area).

    o  The address of the string that is to be matched
       against an element on the list.

    o  The address of a work area used if full string match
       (non-generic) is to be performed.

If the scan is unsuccessful, VCCQSCAN branches to the return
address plus four.  For unsuccessful list scans, VCCQSCAN
branches to the return address.
