Hi. I'm trying to set up a sort of stopwatch program in BASIC, but I'm having problems with the accuracy. I need to be accurate up to the thousanths position. An example would be the time it takes for an object to free fall. If it started at 1.234, and ended at 2.308, I can assume that the time interval is (2.308 - 1.234). How would I go about attacking this problem? I read that there are interrupts which come from the 8253 chip counting up to 65536 every 18 times a second (or some other vague information like that) Does anyone have any experience with something like this, or have you seen any manuals/programmers' references that would cover this? Please EMAIL me with any information, all of which will be greatly appreciated. ...dewitte -- DeWitte Wilson <wilso_d@cs.odu.edu> Old Dominion University Sysop - The Mod III BBS 804-424-1215 [300=>2400] 8N1 "We are the keepers of the Sacred Words.
