/* dispatch control to a function
 * defined by the first letter of the first argument of the XFCN
 *
 * function to logically AND two subsets, and put the resulting intersection
 * of sets into the first of the two:
 *
 *  ("ANDSUBSETS", subsetHandle1, subsetHandle2)
 *  --  returns quietly with nothing if it successfully ANDs all bits
 *      in the first subset flag array with the second array; beeps
 *      and gives an error msg if it fails somehow...
 *
 * function to logically NOT a subset, inverting its contents
 *
 *  ("BOOLEANNOTSUBSET", subsetHandle)
 *  --  returns quietly with nothing if it successfully NOTs all bits
 *      in the subset flag array; beeps
 *      and gives an error msg if it fails somehow...
