calculator-like code entry with matrix keypad and display

[aratti]

this problem is caused by the # value ( and the A,B,C,D keys would cause the same issue

Dennis # character is intercepted by the IF/Then condition and the added " goto ini " command should have solved the issue. As far as A,B,C,D and F just place a trap with an additional IF/then condition. See the example:

If KeyPress >57 then Ini
If KeyPress = "*" then goto retry

Since only "*" ; "#" and numbers from "0" to "9" can pass the if/then condition, this should solve the problem.

Take care.
