hp 42s programming Message #1 Posted by William L. Drylie on 10 Sept 1999, 2:47 p.m. I need help finding a corresponding keystroke or sub routine for the 42s that corresponds to the regswap command in 41cx programming. I have an old hp67 program I use frequently in my work that is rewritten for the 41cx and I want to use it on my 42s. The 67 program used the primary and secondary register exchange, the 41cx used a specific block of registers specified by size of block and location to exchange data. I can find no corresponding keystroke sequence in the 42s manual. Maybe someone else has run across this problem? If someone has a solution I would appreciate the help, or drop in and say hello. Thank you.

The Instruction you refer to is part of the card reader translation library for 67 41 compatability. The best I can suggest is a subroutine to do the swap for you.

I have a subroutine written already, but I am exploring the possibility of using matrix row swap with the 42s. I havent really explored it yet but it may have promise.
