Re: C43 bezel expected when?
Waaayyy back in spring 2020, Martin, Pauli, and I specified - after comparing vintage HPs and a Pantone card under Australian sun - yellow (130 PC) and blue (306 PC) for the WP43. AFAIK, these were used for printing on the pilots. The colours of their plastic shift keys deviate for sure. 305C and 1...

Re: C47 - missing LINE function
Could we consider using complex numbers to define the graphical coordinates?
Perhaps also have each axis ranging from zero to one as a real rather than an integer?

Re: C47 - missing LINE function
If someone volunteered to implement more, I'm sure they'd be considered for inclusion.
Otherwise, they'll have to wait for one of the team to build up sufficient motivation to design and implement them.

Another saving is avoiding the LocR and using the lettered registers which (I think) start zero filled.

Re: Show all digits of a huge integer
I fiddled a bit last night until the emulator randomly exited, so nothing concrete yet. The zero problem can be avoided by using FIX display and storing the digits in the fractional part or using integer mode with leading zeros enabled. It should be possible to get thirty or more digits per register...

Re: Show all digits of a huge integer
Sounds like a job for a short keystroke program. Break the number up in, say, twenty digit lumps and display or store in registers.

Re: DM43/C43 emulator for MacOS
I just run `make test` at the top level and it all works. Not sure what the difference is since looks like it's doing the same commands.
