calculator-like code entry with matrix keypad and display

[aratti]

......So the problem now is how to get numbers which are less than 3 digits to work.
For example if I enter the number 99 I get 227 in MCS serial tool
Another example is the number 1 (single digit) shows up as 195

I am trying to figure out why but can't see it as yet.

Dennis the reason is that the array are no cleared. Add the three lines in red to the previous snippet and you are in business

Al.

Array var Byte [3]
A0 var byte
B0 var Byte
KeyPress Var Byte ' will contain the ascii character of the key pressed

A0=0

Ini:
If KeyPress = "#" then

if A0=2 then
B0= (Array[0]*100)+(Array[1]*10)+Array[2]
HSEROUT [B0]
endif

if A0=1 then
B0= (Array[0]*10)+Array[1]
HSEROUT [B0]
endif

if A0=0 then
B0= Array[0]
HSEROUT [B0]
endif

A0=0
Array[0]=0
Array[1]=0
Array[2]=0
ENDIF

If A0>2 then Ini

Array[A0]=KeyPress -48
A0=A0+1
goto Ini

PS. Dennis the matter was just more complicated so I added the complete correction. I sure you will understand where the problem was.
