Re: buttons that don't register well

But after adding two little strips from a Post-It, it's significantly better than it was originally. Could you please explain your two little strips from a Post-It trick? I can't wait to try the flexing fix to the stiff keys of my DM42 but am worried that I might make the ENTER key worse, and will ...

Re: Python to RPN converter

new subforum to post Python programs Sounds good - not sure how to set that up - have PM'd you to discuss. Alternatively, people can create examples on the Python to RPN website itself, and when they are voted for (there is a link under each user created example to vote), they can become part of th...

Re: Python to RPN converter

I try to convert a simple program to find the sum of all divisors of a given integer, just for testing The Python % operator (modulo) was not being converted to RPN’s MOD - this has now been fixed. Please try it again! Note that at runtime you will get an error about for loops being limited to a th...

Re: Printing freeze

And the other issue I'm getting is that the 82240B printer itself sometimes freezes - seems to be prevalent in trace or norm modes. See attached screenshot - notice the black block that gets emitted immediately prior to the freeze. The red light on the front of the printer goes out and I have to tur...

Printing freeze

Printing to my 82240B I sometimes get the printer stopping and the DM42 is frozen. The printing symbol is displayed and a ((.)) symbol but the DM42 does not respond to keypresses. Cannot turn it off, cannot interrupt it with R/S. I have to do a complete memory reset with a paperclip in the hole on t...

Re: Python to RPN converter

New release today - Converter page now has a Clear button and a New Project link - as well as no initial demo code - nice and clean. A new LBL main start point for programs is the new default, allowing access to the Python global scope area - great for sharing variables between functions. Programs w...

Re: buttons that don't register well

I've received a DM42 from the recent February 2018 run. Nice - but keys are stiff. I also had the ENTER key issue where it only registers if you press on one side of the ENTER button. I can confirm that it is possible to fix, as I read in this forum thread, by adjusting the right hand side screw (wh...

Re: PUSH/POP stack

Nice algorithm- thanks.
In the first version, modifying it slightly to leave out line 29 will restore XYZT as it was, which I prefer. Then if I happen to want what was in X prior to calling POPST, I can do a LASTX.
