Re: Feature requests

... REM "comment" RCL+ 17 ... In a keystroke programming model you would have: step xxx REM step xxx+1 "comment" step xxx+2 RCL+ 17 The new REM instruction would just skip the next step to avoid putting the comment string in the Alpha register. You can already do this with: step xxx FS? 52 step xxx...

I'd vote for inline comments - something like

RCL+17 /* comment

allowing for commenting each step.
How would you implement this in a keystroke programming model such as the 42S one? /* would obviously be translated to divide and multiply instructions...

Re: How to enter a right pointing triangle into a string in prgm mode?

The DM42 encoder/decoder is a good place to create such strings.
For example enter in the listing windows:

Code: Select all

01▸LBL "TST"
02 "A▸B"
03 AVIEW
04 STOP
Encode and dowload the .raw to your DM42 (or Free42).

Re: DM42- clock losing time

I concur. Does anybody know the pins where a quartz could be added to make precise timing possible? As far as I can see on my DM42 there is already a 32.768KHz quartz (or oscillator) loaded (Q1). So I think that improving the accuracy may be done in software using some of the techniques described i...

Re: 8 Level Stack?

This is already available on the WP 34S: each program/subroutine can allocate from 1 to 144 local registers and doing so get access to 16 local flags named .00 to .15

Re: Statistic

It seems that you don't have enough registers available. If you do RCL REGS what is the size of the REGS matrix in X? You can allocate more registers with the SIZE function (shift MODES down arrow) For example SIZE 0025 should be enough. Another possibility is that you have inadvertently deleted the...

So, finally had some time to draw this modules port expander:
What kind of modules are you considering ? What would be the hardware interface to the DM42? How would they be supported in the DM42 software?

Re: SUM, MEAN & SDEV don't lift the stack

So the only exception from a sensitive stack handling seems to be the HP-29C/19C as reported by Thomas. And the HP-67, 41C, and 42S, which may go back to the HP-65 in this matter. Have to check. The first HP calculator with 2 variables stat functions is the HP-55. On the HP-55 MEAN and SDEV are ove...

Re: SUM, MEAN & SDEV don't lift the stack

On the 32s and the 32sii you recall separately the mean of x and the mean of y, not both at the same time. If you recall the mean just after the last Sigma+, it replaces the content of X (stack lift is disabled after Sigma+), if there is another operation enabling stack lift after the last Sigma+ th...
