OK, I've done it. I've made a site for code and tips. I'll take anykind of code for any board. The site's up, but barren. I'm leaving town tomarrow, and don't have enough time to get any code listed. I wanted to get it up so everybody can look at (...) (27 years ago, 17-Jul-99, to lugnet.robotics.handyboard)

I can offer that in my C++ course I learned that in order to pass a variable name into the array size declaration, it must be a const int type. Don't know if that's true for Ic, but if it is, you'll be able to keep your cycle_length variable. (...) (27 years ago, 16-Jul-99, to lugnet.robotics.handyboard)
