Sorry, Forgot to enclose the code. what is wrong here? long time; void phony() { while (digital(2) == 1) { time = mseconds(); printf("%d\n", mseconds()); } if (mseconds () >1413 ) fd(1); else bk(1); } void start() { phony(); } void main() { while(1) (...)

(...) whoa! Local function definitions. Even GCC doesn't grok that. Try extracting the function definition phony() from start() like so: long time; void phony() { while (digital(2) == 1) { time = mseconds(); } } void start() { phony(); } -d (...)

[John Bachman] spake unto the ether: (...) You have the definition of phony() nested inside the definition of start(). I don't know what ANSI C and/or C++ let you do, but this is invalid IC. You need something like: long time; void start() { (...) (25 years ago, 13-Nov-99, to lugnet.robotics.handyboard)

I am having trouble with function definitions. Can someone tell me what is wrong with this: void detect_time_2 (void) { code here;} I get a syntax error on the definition line and cannot figure out why. TIA John (25 years ago, 12-Nov-99, to lugnet.robotics.handyboard)
