RPN programming model survey

[David Hayden]

Line number addressing is a pain. The 35s attempts to make it better, but it still falls short for the reasons already mentioned. Labels are a lot easier to use.

I think the 35s method would have worked okay if the GTO adjustment had worked across labels. Sadly, it does not, probably for performance reasons.

In other words, I think the workflow should have been like this:
1. Write and debug your program using label addressing.
2. Once the program works right, delete all the internal labels. The calculator converts the GTO/XEQ [label] to GTO/XEQ [line number]

The wouldn't be perfect. It might still be hard to develop large programs, but short of adding more labels, I think it would have been a great addition.

Oh, and local registers/flags similar to the WP34s should be required on any new programmable RPN calculators .
