| | for loop stack overflow
|

THis may be a dumb question on my part, but we are getting stack overflows on for loops such as for(int i = 0;i<1000;i++){...} when using values over 100 or so. Is this an 8bit counter thing or something else? Thanks, Owen Popplestone (26 years ago, 20-Oct-99, to lugnet.robotics.handyboard)
