Easiest groups/lineages of machines to port software between?

Using indirection is just one example: the 32s uses positive indices to address the variables A–Z. Which is ok due to its limited memory. The 35s uses the same indices for its huge extended memory (800+ variables), while the variables A–Z are addressed by negative indices.

I wouldn't be so sure without seeing the program. I was reading the 35S bug list yesterday, and it mentioned the silver going into an infinite loop with certain programs containing looping. This could be one of those cases. Would have to see the code to tell, of course.

I have the module, but have never used it.

Yes, but still worth mentioning. Impressive that it could convert RPN keystroke programs to BASIC.
