On the DM42 and the HP-42S, your numerical storage registers are part of the "REGS" matrix. If you delete that matrix or if it doesn't have enough elements to store the register you want to access (e.g. in your example STO 01, the matrix should have at least 2 elements, 00 and 01) then you get this error.

To get further i resetted the calculator which (as you might expected) solved the issue.
I do not remember deleting a matrix but i'm a real noob on the machine.
If it happens again i'll check.
Thanks.
That creates a new matrix with room for 25 registers, which is the default on the HP-42S. Personally I tend to allocate room for 100 registers on the DM42 because there's plenty of room for them.

You can also use the SIZE function in the MODES menu; it will set the size of REGS to the desired number, and create REGS if it doesn't already exist. To set SIZE 25, type

[Shift] [+/-] [▼] [Σ+] [2] [5] [ENTER]
Thomas, is there a missing keystroke your operation? I just ran into this problem and want to set the size of REGS each time the program is run.

Shift +/- Down gives me a soft menu that has Size on it but you didn’t use it. You went for the Sum+ button. I guess I do t understand why pull up the menu and not use a menu item. What am I missing?

Oh, I see... [Σ+] is the first menu key in Free42 and on the HP-42S, but on the DM42, you have to press the leftmost soft key instead, since the [Σ+] key executes the Σ+ function there, even if a menu is active.
