Ah, but any compiler that has optimization capabilities that would allow it to nullify a useless program invariably does not do such optimization unless you ask for it with flags such as -O. My guess is that you don't optimize such a program during development, only after development is nearly complete. Mike McNelly mike%hpfcla@hplabs.hp.com
