You must not key in 40 [LBL] [A], but 40 [A].

Any input different from 0 should return 0. This confirms that the input has been stored.
If you see anything else the program has calculated that value.

Take a look at the test commands, i.e. the x≠y? tests following LBL A, B and C.
The sequence alsways is...

Code:

LBL (A, B or C)
STO (1, 2 or 3)
0
g x≠y?
RTN
g NOP
...

Be sure to use the "x not equal to y" test.

You must not press 50 [LBL] [B] but 50 [B].

will return a weird value.

I can't reproduce this. May someone else try the program in post #5 and report his results?

but I would like to understand what am I doing wrong, so if you have time I will appreciate any further comment

We will get this running, even if it takes more posts. Maybe there still is an error in the program, maybe you entered something wrong. Have you compared the key codes?
