Fred, Man, do you ever sleep? I hope you know how much your support is appreciated. Here is a copy of my jrm1.c file. Just a reminder, if I type " main() " in the IC window on my PC, this file executes flawlessly. Thanks, John /* filename: jrm1.c (...) (24 years ago, 31-Dec-01, to lugnet.robotics.handyboard)

Fred, I double-checked, and my " main() " program (filename: jrm1.c) is all lower case letters. I confirmed case sensitivity by trying to call the " main() " file (filename: jrm1.c) which has been downloaded to the HB by typing " Main() " on the PC. (...)

I wonder if it's because you've capitalized "Main()". C is case sensitive so main != Main. try it making your main program lower case and see if that works. Fred (...) (24 years ago, 30-Dec-01, to lugnet.robotics.handyboard)
