The fragment you have above is designed to run under VAX Unix, not VAX/VMS. The Unix compiler for C normally does support the asm call. This is a bad idea, for all sorts of reasons. Questions of compiler optimization, variable naming, and portability are all important when trying to do in-line assembly language. +-------------------------------+ | Joel M Snyder | BITNET: jms@arizmis.BITNET | Univ of Arizona Dep't of MIS | Internet: jms@mrsvax.mis.arizona.edu | Tucson, Arizona 85721 | Pseudo-PhoneNET: (602) 621-2748 +-------------------------------+ ICBM: 32 13 N / 110 58 W (I have gotten into trouble too many times to put any faith in disclaimers) "There's nothing here that an overdose of Seconal won't cure."
