=1=1=1=1=1=1=1=1=1=1=1=1=1
My stack has; (after pressing ENTER)

1:  ::  x<< % 2. x+ x'
     ID ADD2 x' x>> ;

When I press 'STO'
the message

! STO Error:
Bad Argument
Type

comes to the screen in a shadowed box.
and the contents of register 1 are still there

=1=1=1=1=1=1=1=1=1=1=1=1=
Note; I had HP41C calculators for many years and appreciatel RPN
However they have quite functioning and are more expensive to fix
than a new 50g.
The 41 had an instruction book that was worth while; the 50 doesn't!

The 48 & 49 manuals that I have found are helpful and close to the 50
BUT the programs do not enter without getting BAD ARGUMENT messages, thus far.
