        This function is executed when an {\em op\_call\_rss} opcode is
        encountered in the binary makefile. Following this opcode a function
        index is expected (an {\em char} value), indicating the function number
        to call (see the enumeration type {\em FUNNR\_} in the file {\em
        icrss.h}).

        If the index indicates a non-existing function, i.e., when the index
        exceeds or equals {\em f\_hlt}, an error occurs. Else, the indicated
        built in function is called (see the {\em builtinfun} array of function
        pointers, files {\em icm-exec.h} and {\em data.c}).
