Insert hyphen in string character

[Moise]

Hello, 

I have a string character like that AB032001ZWXY and I have to convert to AB-032-001-ZWXY by inserting hyphen, how can I do that?

Thanks

target = catx("-",substr(source,1,2),substr(source,3,3),substr(source,6,3),substr(source,9));

Set the required length for target before this with a LENGTH statement.
