WP-34s port to DM42

[Nigel (UK)]

Just to let you know: the WP34C version of the WP34S is now available for the DM42. This includes a "Complex Lock" mode that aims to make the entry and use of complex numbers more straightforward than on the WP34S.

This version also includes:

• Entry RPN. If you don't want the first press of ENTER to push the x-register into the y-register, this is for you.
• The stopwatch! I never installed a crystal in my WP34S so this is my first experience of it. It's good!
• IR printing! This seems to work well on my HP 82240B printer, so it will probably work on yours too. I don't see how my code could harm your printer, but if your printer is particularly precious to you, perhaps you should not try this.
• A user-defined menu system, based upon the (never-released?) user catalogue code that I found in the WP34S source.
  

You'll find the WP34C in the wp34c branch of the gitlab project linked to before - here is a link to this branch. The files - wp34c.pgm, wp34c_long.pgm, wp34c_top.pgm - are in the build/ folder. Some information about the user menu system, complex lock mode, and entry RPN is available in the help/ folder.

If you have no use for complex lock mode or for printing or even for entry RPN, don't worry. If you don't activate these features they make no difference to the calculator's operation. The WP34C really is a WP34S, but with extra features there if you want them.
