KeyPad Data
I have a 16 key keypad attached to my stamp through a 74c922 decoder.
Here is my problem. I need to enter a numer from the keypad: Example
85 and store that number in to a varible.
How do I write software that will alow me to enter more then one
number and put the that combination into one var.
Right now i press one key to increase the number and an other to
decrease the number then that total will be stored into a var.
Thanks!!!

Mohamed's reply was correct. Take the following code for example...
Buffer var byte
Key var byte
Buffer = 0
Main:
' Get your key value and store it in "Key"
Key = [noparse][[/noparse]Key value]
' Shift Numbers in Buffer one place to the left
' And add your last key value
Buffer = Buffer * 10 + Key
Goto Main
When you start the program Buffer is set to 0. Now lets say you press the
key "1"
Buffer = Buffer * 10 + Key
or
Buffer = 0 * 10 + 1
so
Buffer = 1
The value in Buffer now equals 1. Next you press "2"
Buffer = Buffer * 10 + Key
or
Buffer = 1 * 10 + 2
so
Buffer = 12
And just to prove it works for zero..
The value in buffer is now 12 and you press "0"
Buffer = Buffer * 10 + Key
or
Buffer = 12 * 10 + 0
so
Buffer = 120
The only limitation to this code that I can see is that you can't have
leading zeros (002 for example), but it should work for your values of zero
to 200.

so that when that key press is detected the loop which is collecting key
presses
knows when the number is complete. Like this....
Buffer var byte
Key var byte
Enter_Key var byte 'this is the value to look for
'as the enter key.
Buffer = 0
GetInp: 'was Main:
' Get your key value and store it in "Key"
Key = [noparse][[/noparse]Key value]
If Key = Enter_Key GOTO SetInp
' Shift Numbers in Buffer one place to the left
' And add your last key value
Buffer = Buffer * 10 + Key
Goto GetInp
SetInp:
'Now we have the desired value
'do whatever with it....
'
'Dont forget to check for new keypresses now and then..

Tobin,
Mohamed's reply was correct. Take the following code for example...
Buffer var byte
Key var byte
Buffer = 0
Main:
' Get your key value and store it in "Key"
Key = [noparse][[/noparse]Key value]

Buffer = Buffer * 10 + Key
Goto Main
When you start the program Buffer is set to 0. Now lets say you press the
key "1"
Buffer = Buffer * 10 + Key
or
Buffer = 0 * 10 + 1
so
Buffer = 1
The value in Buffer now equals 1. Next you press "2"
Buffer = Buffer * 10 + Key
or
Buffer = 1 * 10 + 2
so
Buffer = 12
And just to prove it works for zero..

Buffer = Buffer * 10 + Key
or
Buffer = 12 * 10 + 0
so
Buffer = 120

Take the first number 8 and multiply it by 10 then add it to 5 you get
85.When You press a third number for example 2,take the last valu 85 and
again mupltiply it by 10 then add it to 2 you get 852.
So you always take the key value and add it to the last value mualtiplied
by 10.First Number must not multiplies by 10 unless Basic Stamp receives
the secnond number 5.
