Hi! Back again with more problems. I want to use random() in my programs and looking in stdlib.h it looks like it is implemented. It says: extern long int random(void); extern void srandom(unsigned int seed); When I didn't have stdlib.h included, I (...) (24 years ago, 22-May-00, to lugnet.robotics.rcx.legos)
