It calls the filename matching routine that is in the F11X facility.  DCL's SHOW SYMBOL calls the same routine.  SHOW LICENSE also.  I found other calls scattered around.  Same as STR$MATCH_WILD (both written by AndyG back in the Mesozoic era) in functionality but STR$MATCH_WILD uses descriptors.  Guy added the lexical back in 2005.
