        This function is executed whan an {\em op\_call} opcode is read.
        Following the opcode a 16-bits unsigned value is expected, stating the
        offset of the function to call.

        The offset of the next instruction is pushed as an {\em e\_int}
        variable. Then the file pointer associated with the binary makefile is
        set to the offset of the called function.
