Thats a thought I should follow up on. I'm going to make a "use A" checkbox in the post gui but that might be a timing problem. I'll concentrate on the checkbox first, then figure out how to use it. Or maybe a postgui for the postgui? Two separate configs means it will be hard to keep them in synch, a headache I'd druther not have. AFAIK, the ini can't use an IF, and neither can hal. That would be a welcome addition, so one could build his config on the fly as it was loading based on ENV settings that could be set with a wrapper script. Hint hint... Or a bash wrapper to assemble the config according to ENV vars? I suspect there are at least 50 ways to skin this cat. ;-) > > > > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
