    To be even more specific, the GOSUB will put a return address on the top of the "Stack" It will remain there forever (as long as the PIC is not reset) until a RETURN is executed. So, Steve's 2.7894235e+128 GOTOs do nothing to modify the address on the top of the stack. And, no matter when the RETURN is executed, the program will return to that address.

    Ahhhhhhh , I was really looking forward to it. My stab at it was just a down and dirty continuation of what Steve was getting at. We'll let Sayzer and Ryan weigh in on whether it worked for them.

    Thanks for this simple and clear explanation SteveB.

    I was expecting DT to come up with really complex explanations. heheh

    I was going more for ... Cool!

    Well, since we don't need the explanation anymore, I'll leave it at this, since it's already done.

    Holy Gif!

    DT, I can't believe you made it within half an hour!
    What can I say? It is just as you said it was.




    rhino,

    I now see that you were in a different page then I was.

    But, you had your answer and I had mine.


    Thanks to all.

    I enjoyed watching posts coming in and out, too.

    Especially this last post by DT!

    Yep... makes sense. After all of your responses and looking at the manual for BranchL...
    Quote Originally Posted by TFM

    second Label, and so on. If Index is greater than or equal to the
    number of Labels, no action is taken and execution continues with the
    statement following the BRANCHL.    ....(hence the RETURN)
    I guess seeing that return in Darrel's code was throwing me off, but now it I see why it's in there. It looked to me like a way of nesting subroutines. Both of the Steves explainations of how the return address in the stack works answers one of the questions I didn't even ask.... scary! Thankyou all.
