Split decimal digits

[sayzer]

Dig is great function but how to find out how many digits in the number if you dont know it, and what Dig function will do if you try to asses position what do not exist ?
W0 = 54321
B1 = W0 DIG 6 <---?

What I get from the question is this:
W0 is WORD

Say W0 = 23.
That makes it W0 = 00023.
IF you want to know which digits are NOT zero then you need a "check" routine.

Example: W1 = 00103. We have two zeros we do not need. So DIG3 and DIG4 are not required to be read (for some logical reason!)

I think this is what the question was asking.
In that case, starting from Left to Right, we have a check routine.

IF W1 DIG 4 = 0 THEN
 IF W1 DIG 3 = 0 THEN
...

ELSE
'Do something....
ELSE
'Do something....
....
etc.

Do I make dead comments again?

Hi,
I don't really follow you here....
A word is always 16bits (0-65535) so yes, 5 digits. Digits "not used" will return a 0 when used with the DIG operator. If you are using the DIG operator for display purposes and don't want to display the zeros you need to use a check routine like in Sayzer's example.

I just wanted to build couple 7 led displays so I was thinking about how to measure how many digits in the number to send each number to led display
