Thanks for all the helpful device but the darned thing still does not work. I have created a simplified program to try to figure out what I am doing wrong. Here it is:
/* A simplified program to figure out what is wrong */
long time;
void start()
{
phony();
void phony() /* Line 9 syntax error is reported here */
{
while (digital(2) == 1)
{
time = mseconds();
}
}
}
When I try to load it with IC I get a syntax error on line 9. Can anyone tell me why?
TIA

| [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)

| (...) 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 (...)

| 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)
