Hi Victor, I'm sure you will receive some wonderful suggestions from this list in regards to your situation. Let me begin by suggesting the use of an xtra to gain information about the end user's processing capabilities. Buddy API can return the following information about the user's CPU. InfoType is the type of information to get. Can be: "vendor" the processor manufacturer "type" returns the type of processor "model" the model of the processor "stepping" the stepping revision number "speed" the speed of the processor in MHz You can get more information at: http://www.mods.com.au/budapi/ Hope this is at least a start, g fritzinger [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/LUJ/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]) Lingo-L is for learning and helping with programming Lingo.
