PIC, Basic language question

[rezaf]

Hello
I work on a project similar to calculator but have a problem and be happy if someone help me. in this project there are PIC16F887, keypad and GLCD that user must enter numbers. I want similar to calculator the user able to enter numbers and see on GLCD and then the numbers save in a variable but I can't save all numbers that enter in a one variable and always the latest number save in variable please help me to resolve this problem. I write my code in basic language. the number is 3 digit and have decimal (for example 2/5 or 2.5)
I can't show decimal point on GLCD and save to variable too.
thanks for your helps.


wl:
T6963C_GrFill(0)
T6963C_TxtFill(0)
T6963C_write_text("Please Enter number !", 2, 4, T6963C_ROM_MODE_XOR)
T6963C_write_text("the Number : ", 2, 8, T6963C_ROM_MODE_XOR)
T6963C_write_text("9.Return to Home", 14, 15, T6963C_ROM_MODE_XOR)
cnt = 0
wlset:
do
kp = 0 ' Reset key code variable

' Wait for key to be pressed and released
while (kp = 0)
kp = Keypad_Key_Click() ' Store key code in kp variable
wend

select case kp
case 1
kp = 1 ' 1
case 2
kp = 2 ' 2
case 3
kp = 3 ' 3
case 4
kp = 4 ' 4
case 5
kp = 5 ' 5
case 6
kp = 6 ' 6
case 7
kp = 7 ' 7
case 8
kp = 8 ' 8
case 9
kp = 9 ' 9
case 10
kp = 46 ' * ,decimal point's Ascii code
case 11
kp = 0 ' 0
case 16
kp = 68 ' D
end select
loop until kp>0

if (kp = 9) then
goto home
end if

do
inc(cnt)
if (cnt = 1) then ' I try to resolve my problem by this codes but can't.
wl1 = kp
goto wlset
end if
if (cnt = 2) then
wl2 = kp
goto wlset
end if
if (cnt = 3) then
wl3 = kp
goto wlset
end if
loop until cnt>4

wl = wl1&wl2&wl3 'wl is the variable for 3 digit number
ByteToStr(wl, txt1)
T6963C_write_text(txt1, 15, 8, T6963C_ROM_MODE_XOR)
T6963C_write_text("unit", 22, 8, T6963C_ROM_MODE_XOR)

One way is to save all the numbers to an array and then make the conversion to a single number.

the compiler can't convert array to integer or word and when I want to convert to string to display on GLCD give error too .how to convert array to one integer?
