NQ41 Emulator program testing

[Craig Bladow]

I'm developing tests for the next version of NQ41. These tests run on the HP-41C and then run on NQ41 to see that the operation is the same. I've included an example below. I'm interested in suggestions regarding other programs that would be useful for validating the emulator. NQ41's numerical precision is different from the 41's so demonstrating equivalence in this area is not necessary.


This code performs various GTOs and XEQs and leaves a "1" in the X register if successful.
