Just noticed one thing: if you move to the <Parent> directory from the PROGRAMS or STATE directories, then both of them are not listed and you cannot go back. https://forum.swissmicros.com/download/file.php?id=383 That could be due to an accidental unclean unmount / eject some time in the past, lea...

I understand the next DM42 update is soon to be announced, so I should think it will incorporate a more recent release of Free42.

Early on I found the VARMENU and MVAR statements. These worked fine for my code but I found I could not access my memory variables ( I have a bunch of constants in named variables ) easily without exiting the program. So I switched to INPUT statements. This worked much better for me. I can now use ...

It seems intuitive that there should be more rational numbers than integers, but this is where intuition is wrong. The set of integers and the set of rational numbers have the same size in the same way that the set of even integers has the same size as the set of integers. However, the set of real ...

I am not an expert either, but clearly there are kinds of infinities which cannot be easily compared. While there is an infinite number of integer values, it seems logical that the also infinite number of rational numbers is larger, and real numbers larger still. It seems intuitive that there shoul...

I always supply power via the USB port when updating the firmware from FAT. It seems like a sensible precaution to avoid lock-ups caused by drop in battery voltage, which in turn is caused by increased battery load during the flash erase and write cycles.

There are definitely places where the habit of using EXIT to enter a number can bite you as it has side effects. A safer habit is to press X<>Y twice, as that won't have the side effect of exiting menus, although it does have the side effect of setting LASTx to the number you just entered. Another o...

Explicitly showing the limits of the 4-register stack in calculating is Hans' new contribution to the topic. HP did never mention it in a manual IIRC.

HP not mentioning it is hardly a surprise!

I think the main advantage of the proper stack that can grow and shrink is that it makes it easy to write functions that behave like built-in functions without having to worry about preserving elements that would fall off the end of a fixed 4-level stack.

Traditionally, gifts used to be given on Christmas Day here in the UK but only opened on the day after Christmas, hence the name "Boxing Day".

I suppose in modern parlance it should be known as Unboxing Day (except on YouTube, where every day is an unboxing day!).
