          Yes, he said, blushing.  I wrote it.  It's a pair of
          routines, as I recall (long time since I've touched it).
          One of them builds a few arrays of arguments for the call;
          the other one invokes LIB$FIND_IMAGE_SYMBOL and LIB$CALLG.
          I will get the sources out of mothballs and send them out
          some time in the next week or so, if you can's find it
          elsewhere.

          Currently, the routines only handle integers and strings.
          Maybe they'll evolve.
