It ran fine in 2025 - thanks so much.

I appreciate folks like you responding to these requests.  Sometimes, Maple gets hung up on very nuanced things.

Thanks so much for your help and detailed answer.  Hang means the curser just keeps blinking at a line.  I assume it means, "...just evaluating forever."

I have purchased the 2025 version and will try it.

Finally, thanks for the hints.

Thanks for checking, and thoughts?

@sand15 I have uploaded the file.

It is buggy, so any tips for more reliable coding is appreciated.

Kind regards

@Thomas Richard Thank you so much!

I never would have found that on my own.  :o)
