you sent me a PM, where I was going to basically reply to ask you to start a forum thread, so that everybody may benefit from the time spent.;

The code block you pasted from the PDF contained some formatting characters, I believe. I tried it using notepad first, before pasting into the Propeller tool. It worked out fine.

Here's my reply, and it appears you are set not to receive PM's! So, I'll just drop it here, and you can start a forum thread for the next PASM question.

Well, I pasted it from your code window into my Prop tool, and did not get this error. You probably copied and pasted from the PDF. Might want to use something like notepad to paste into, just to get rid of potential formatting characters that may be present in the PDF. It's good at first to type stuff in as well. Helps with overall memory of syntax, for what that's worth.

I don't think there was anything else wrong, but I did take a moment to format it for better reading.

Formatting is very important. It pays off to format stuff. Often you will see errors just when doing that. Technically, the code will work poorly formatted, but it's difficult to read and understand.

I really would prefer not to do these via PM. It is much better to start a forum thread so that everyone gets the benefit of the time spent. No worries on this one though.

The code I pasted in compiles fine. I've not yet debugged it. You should run it and continue on where you are right now.
