C allows the initializing prototype to be defined in a translation unit other than the one containing the main entry point, and expects that initialization to have been performed when the main entry point gets control. A preprocessor is needed to move the initializing code (GETMAIN; MVCL) from that other translation unit to the one containing the main entry point. I suspect (and Dave Rivers seems to confirm) that there are undocumented facilities in Binder to facilitate this; in effect a built-in preprocessor. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
