I guess there's a bit of a language barrier going on here. I don't really get what you're trying to say...

Hi savnik,

See if I read you correctly.
You want the user to be able to press a series of buttons, on your keypad. You would like the PIC to take this series of separate button values and “string them together” (“concatenate” them). Then use them as a PIC WORD variable in your program.

You are able to read the individual button presses, but are having trouble putting them together to make the variable.

Is that close?

Ok, well that makes a bit more sense to me...

getword:
for x = 0 to 3
Gosub getkey ' Get a key from the keypad
keyin(x) = key 'save the individual keypresses
lcdout I,Line2 + x,#key ' Display ASCII key number
next
outval = ( keyin(0) * 1000 ) + ( keyin(1) * 100 ) + ( keyin(2) * 10 ) + keyin(3)
return

Perhaps somthing like this will do what you want.

getword:
    value = 0 
    for x = 0 to 3
        Gosub getkey                  ' Get a key from the keypad  
        lcdout I,Line2 + x,#key     ' Display ASCII key number
        SELECT CASE x               
           CASE 0 
              value = value + (key * 1000)
           CASE 1 
              value = value + (key * 100)
           CASE 2 
              value = value + (key * 10)
           CASE 3 
              value = value + key
        END SELECT
    next
    return

           CASE 3

Thank you
I wanted something like this

Maybe this is more effectiv:

getword:
    value = 0 
    for x = 0 to 3
        Gosub getkey                  ' Get a key from the keypad  
        lcdout I,Line2 + x,#key     ' Display ASCII key number
        value=Value*10+key
    next
    return

        Gosub getkey                  ' Get a key from the keypad  
        lcdout I,Line2 + x,#key     ' Display ASCII key number
        value=Value*10+key
    next
    return

OH...that is pretty slick...

You want the variable in memory (whether it be a byte or a word) to be:
x = 2.348 ?
