Determining variable length (number of digits) possible?

[Jerson]

I will give a generic answer as my PICBasic skills are weak at the moment

Assume your variable x contains 1000

You can strip out digits like this from Right to left with position 0 at the right (least significant position) of the display

    position = 0
     if x > 9999 then x=9999                  ' restrict to maximum you can display

     while x != 0
         digit[position] = x Mod 10            ' keep the digit
         x = x div 10                                  ' integer divide by 10
         position = position+1                   ' next display position
     end while

This will automatically stop if the value is 1..9 at 1 digit, or 11..99 at 2 digits and so on.
