How do you convert an algorithm to code?

[boroko]

Thanks for all of the input. After working on it a while, I ran into the same problems that you guys pointed out. Here is where I ended up. It required LONGs for me to get it to work right. When I started to look at it, I had no idea how to do it. Why is it that some projects seem to make you need every function or process that you are new at?

Thank you all for looking at it.

Ähhh....

What's about the DIV32-command ?

[boroko]

Thought about the DIV32 way, but I hadn't done either before and figured that the LONGs were the newest, so that was where I would concentrate my efforts unless pointed otherwise.

I'm sure it would work, but I had to have a reason to justify my recent upgrade :-)
