HP35s bug ?

[Philippe]

Hi,

Thanks to Voldemar for trying.

@thomas :
i reproduce this behaviour each time. 
1) I clear all (Blue arrow CLEAR 3 Yes Enter)
2) then i type the program :
blue arrow PRGM
1 ENTER
2 ENTER
3 ENTER
4 ENTER
yellow arrow RTN
C 
3) back to the stack, i type 
10 ENTER
Then the stack show
10.00000007
10.00000007


If i edit the program and remove  the line containing "4", then all works

Now, if :

1) I clear all (Blue arrow CLEAR 3 Yes Enter)
2) blue arrow PRGM
1 ENTER
2 ENTER
3 ENTER
4 ENTER
5 ENTER
yellow arrow RTN
C 
3) back to the stack, i type 
10
I get :
1?
If i type the ENTER key, i have a syntax error
More info :
a) if i type
1. (digit "1" + a dot ".")
I get :
1n ("1n")

Thanks for your help,
Philipe
