 goto commandI notice there is a goto command in robotc, but I am not sure of the correct usage of it. What I want to do is skip to a certain line of code if a condition is met. Is that a possibility?

Re: goto command Hi benroth,
You could use a goto (which is generally not considered good programming practice), but an if-else statement would probably be a much better method: http://www.education.rec.ri.cmu.edu/pro ... f_else.pdf |

Re: goto command Thanks. If I were to practice poor programming and use the goto, how would I do that? Do I need parentheses? How do I point it to the line number? etc.
I found out I could probably do a StopTask, but I can't get that to work either. I put that in according to the help file and it doesn't work. My task is named "third" I put in the following code: StopTask(third); I get the error "possible invalid reference to procedure 'third'" |

Re: goto command Hi benroth_r,
I think I've been responding to your questions here, and on the PLTW forums. Before you try out multitasking, I recommend giving this page a look: viewtopic.php?f=11&t=3341 |

Re: goto command Thanks everyone. I did get around using the goto. I have been using task and function interchangeably. I see there is a difference. Thanks again for all your help.

Re: goto command The programming world thanks you for not resorting to gotos. They are the work of the devil and should be avoided like the plague.

Re: goto command Yes, raptors will come and kill you if you use goto. True story!
