Rob:
    Why not on the FIRST PASS of bind, scan the source and build a symbol
    table that contains
    1: any time a constant or variable is used
    2: any time a function is used
    3: any time a procedure is used
    The final result is symbol table containing a list of each item used.
    The next pass you do the real bind and anything that is not in the
    the symbol table is thrown away.
