Hello, Sometimes I have used a similar strategy: ;;; udos.inc #ifdef ENVUDO #include "/path/to/env.udo" #end #ifdef SUPERBASS #include "/path/to/superbass.udo" #end ;; etc ... In the follow examples, we include a blank file without `#define' or --omacro. (1) ;;; somefile.csd ... #define SUPERBASS #1# ;; udos is not a kind of unix #include "/path/to/udos.inc" ... (2) ;;; somefile.csd --omacro:SUPERBASS=1 #include "/path/to/udos.inc" ... tito ------------------------------------------------------------------------------ November Webinars for C, C++, Fortran Developers Accelerate application performance with scalable programming models.
