Hi all,

I struggle for some time now changing the output of a CF.

Let ( [ 
digits = "0123456789" ; 
len = Length ( text ) ;
num1 = not IsEmpty ( Filter ( Left ( text ; 1 ) ; digits ) ) ; 
num2 =  not IsEmpty ( Filter ( Middle ( text ; 2 ; 1 ) ; digits ) )
] ; 
Case ( 
num1 and num2 ; 
Left ( text ; 2 ) & Case ( len > 2 ; "-" & PLCFormat ( Right ( text ; len -
2 ) ) ) ;

num1 xor num2 ; 
Left ( text ; 1 ) & Case ( len > 1 ; "-" & PLCFormat ( Right ( text ; len -
1 ) ) ) ;

Left ( text ; 1 ) & Case ( len > 1 ; PLCFormat ( Right ( text ; len - 1 ) ) )
)
)

This CF returns the possible digits in an input field in groups of 2 with a
dash.
When there are letters involved, they are also separated from the
number/digits by a dash.

Example input/output:

TA123/TA-12-3
1234JKL/12-34-JKL
123TA45/12-3-TA-45

I need an additional output form when the numbers are a group of 5 digits.

TA12345 needs to be TA-12-345
12345JK needs to be 12-235-JK

By now I know I have to test not only for the first 2 characters, but also
for 3 and 4.
Reason is, if 3 is a digit, and 4 not, I need to output 3 characters and a
dash (instead of just 2 and a dash as before). 

So, I need to keep the output like it is now, only when there are 5
consecutive digits, the return needs to be a group of 2/dash/group of 3,
with possible letters.

Any hint, idea, solution....?
