Go to Research Systems Inc (www.rsinc.com) and get a copy of IDL. The Linux version of IDL 5 should work fine. You will have to learn their bastardised Fortran/Motif mix, but as a tool for what you're trying to do it's *very* difficult to beat. This will, of course, mean beating on your company's code quite a bit... -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
