Before you do I suggest you get GNAT 3.16a Go to my website http://www.adaworld.com and go to the related links, you'll see an ada download section, select teh 2nd option there. You shouldn't need to change anything to your configuration this way. I didn't need too. Since your new to Ada (welcome aboard :-). and in the "Learning center" in the Tutorials and Free books sections you might find some stuff of interest to your learning . If you really want to stick with Ada 3.10 then in your config.sys add the following line device=c:\windows\command\command.com /e:4096 his is where the enfironment space is set. But I recommend you get GNAT Ada 3.16 and take it from there. -- St�phane Richard "Ada World" Webmaster http://www.adaworld.com "BijanM" wrote in message news:8efab0cd.0310110941.5982c54d@posting.google.com... > Hello > I wonder if there is anyone that can help me. > I am a newbie in ADA95 and GNAT.
