Working with digits.. how do i.....
I can't seem to find a way to combine 3 nibbles with single digit values
into one bye that hold the values of the nibbles in digits 1 2 & 3.
hopefully I can explain it better with below.
I have:
digita var nib
digitb var nib
digitc var nib
target var byte
digita = 1
digitb = 2
digitc = 5
I want target to equal 125. Can it be done with a BS2P40?

Comments
digita = digita
digitb = digitb * 10
digitc = digitc * 100
target = digita + digitb + digitc
I hope this works. keep your eyes open, the masters for math might be able to
find a better way.

target=(digita*100)+(digitb*10)+digitc
Right?

a for/next loop, but this will save code space.

When nibbles are used to represent decimal digits, it's referred to
as BCD, or Binary Coded Decimal.
Typically, each nibble holds a value from 0 (%0000) to 15 (%1111),
which is the basis for the hexidecimal numbering system where each
nibble can hold a value of 0 to F.
If the nibble value is limited to 9 max (binary 1001) each nibble
then represents the decimal value.
In your example if you only wanted to display the value, we could use
the HEX modifier to display the BCD value:
digita var nib
digitb var nib
digitc var nib
target var byte
digita = 1
digitb = 2
digitc = 5
DEBUG HEX digita,HEX digitb,HEX digitc,CR
Another thing that could be done is define a word varaible, then
parse out its individual nibbles to other variable names alleviating
the need to re-assemble the nibbles and saving memory.
DIGIT Var WORD
Digit1 var DIGIT.NIB3
Digit2 var DIGIT.NIB2
Digit3 var DIGIT.NIB1
Digit4 var DIGIT.NIB0
Digit1 = 1
Digit2 = 2
Digit3 = 3
Digit4 = 4
DEBUG HEX DIGIT,CR
