I may be making silly mistakes, but I cannot type a _ in the file name (for wp34s_top).
I don't know where you are trying to type a '_' , but if it's in Setup menu SvRAM command, then the '_' character is available through the F1 key.

I also excited the program numerous times, and it seems not to auto save a name.
For me every time I press EXIT in the Setup menu, the file wp34s.dat in the wp34s directory is updated, both with wp34s.prgm and wp34s_top.prgm.
Sorry I was trying to use - and +.

I changed to EXIT.

f[0] EXIT, [2] (run program) and every time it still states "can't open".

In the Setup menu press OnSTO once to create a backup file, this worked for me and removed the "can't open" message.

When the calculator program first starts it tries to load three files - the file containing the calculator state (RAM file), a backup file, and a library file. Your message means that at least one of these three didn't open, probably because it didn't exist!

The library file is compatible across all three versions.

The RAM file is written whenever you EXIT the program. You can also write it by hand using SvRAM in the SETUP menu; use a file name of wp34s.dat or wp34s-4k.dat . A backup file can be created using OnSTO, also in the SETUP menu.
Thanks, the RAM and libray files were present but not the backup file, so I pressed OnSTO in the SETUP menu and that solved the issue: no more "Can't open" message.

Have you changed the menu display management? After pressing OnSTO the menu went fully blank, but the keys retained their functions from the Setup menu.

I also noticed that Shift ASSIGN is no more toggling the default menu as it was previously and as described in the help.
I tried f[0] OnSTO [EXIT] EXIT [2] (run program) and still "can't open".

You may miss also the library file. I'm using the standard wp34s-lib.dat file from here that I copied in the wp34s directory on the DM42.

This worked.
I did not load and store that manually.
Now no more "can't load".

I haven't intentionally changed the menu display management, but something that I have done means that the menu is not always being redrawn properly. Shift ASSIGN is still working, but the menu isn't being displayed. It must be a recent change that I have made ...

Both of these problems had the same cause - a single line of code had gone missing, near where I had been doing some editing. I've uploaded the fixed files.

Perfect, with the latest files the menus work as expected. Thanks for the quick fix!
