The folks who invented FORTH had an office down the hall from me for years. Really nice people and mega-talented. Oddly enough I currently use the three most hostile programs I have encountered: R, sendmail and MS Exchange Server. In my opinion user hostility is nothing more than self indulgence on the part of the developers, but then I guess those who program for free are entitled to be a bit self indulgent. So what is Exchange Server's excuse? --jab
