splitting a $var in half

Hi - have searched the forum, but can't quite find what I need.

Just wanting to split a $var in half and insert another character in the middle.

eg. make: $abcdef into: $abc-def

The $var is always 6 characters long, and the split I want to make is always in the middle 3 and 3.

Thanks for any help!

Try this...

Code: Select all

set var "[string range $var 0 2]-[string range $var 3 5]"
