Re: 43S News

Now let the flames begin. We will firefight but stay always open to conviction. Though don't forget who are the developers of this forthcoming device. Yes I don't forget who are the developers and I fully appreciate all the work being done. And I know that at the end the decision is in the hands of...

Hey Walter don't take this discussion too seriously ! Did you see the smiley ? There are way more important things in life than keys order on a calculator keyboard ;)

Re: 43S News

Jaco, I have to say... Your modified/unofficial layout is *exactly* what I would prefer myself: 1) Math operators on the right --- just like the 34S and other "late" RPN calcs 2) top-to-bottom order of math operators matches 34S and other late RPN. 3) XEQ / ↑ / ↓ / EXIT on left with same order as o...

Re: [DM15L M1B V28] Using R/S in a subroutine reached by line number wipes the call stack

How would you go about writing your own gosub stack? Do you mean use GTO I with flags and such to simulate a GSB/RTN ? Not sure, one way would be to put the stack pointer in register 0, having it contain the register number that contains the line number to jump to on return. There is an easier work...

Re: [DM15L M1B V28] Using R/S in a subroutine reached by line number wipes the call stack

This seems to be a bug of the original 15C firmware that was fixed by changing the manual to remove the reference to GSB I with I<0. See this discussion .

Re: Another 43S poll

I voted for b) because in a ) the meaningful information represents only 3% to 6% of the displayed pixels with the other pixels being identical for each function, which is not the best way to easily convey the right information to the end user.

Re: DM15L programming

It doesn't strike me as a feature that would be super difficult to add. Simply modify the simulator's display routine to snoop on whatever flag/register/memory address is used internally by the calculator to indicate that it's in program mode (or that SST is being held), and use an alternative disp...

Re: A problem of Conditions

If i have a condition in a program (for exemple a booleean : 1 if it's "yes") on A : for exemple if A>10 ,i =1 and else i=0. For boolean I would suggest using a flag instead of a variable : 38 CF 00 /* clear flag 00 39 RCL "Achar" 40 10 41 X<Y? 42 SF 00 /* set flag 00 Then you can easily test if th...

Re: [POLL] Compiler for DM15L ?

There is already a Python to RPN converter for the 42S, do you plan to do the same for the 15C?

Re: External stack

Ok, the WP 34S got local registers in 2011, Free42 got local variables now. Beyond the difference between registers and variables, is there anything else? Just for curiosity... AFAICS: On the plus side for the WP-34S: LocR is allocating local registers AND 16 local flags. There is so far no local f...
