The Compare Wild Card command provides a comparison of a system name against a
compare value that contains fixed and/or floating wild cards. The companion
command is CHKWLDCRD which is intended to be used before performing a function
such as a DSPxxx OUTFILE or when using a list type API. Additional commands
CMPWLDCRD2 and CHKWLDCRD2 may be used on any string (up to 500 bytes) such as
customer names or addresses.
