Acer, Thanks for your reply. The code I'm working on is the Viterbi algorithm. It's not big and I'm using the RowDimension command once. I might need to implement it one more time. Legibility is fairly important, since my project is creating Maple sheets that act as introductions to Maple as well as Markov models to a Biological modelling class. I don't expect the students to being able to understand every Maple command involved in the code, but I do hope that, if the wish, they can follow along and get a good idea of what is going on. This has been my first foray into Maple, starting in January, and I've been enjoying it. I have very little prior programming experience, so understanding the algorithm was a challenge, but I'm very happy with what I'm getting out of it.

Thanks! That works perfectly great!
