TMTOWTDI

I'd use
s/(\D{3})(\d{4})/$1-$2/

It's a little more robust when the abc1234 is not the only thing on a
line.

I presume the format is originally
3 letters 4 numbers?

If so:

s/(^[a-z]{3})(\d{4})$/$1-$2/;

Why didn't I think of that B-{)))

Yes, you're right.

In order for $1 (etc) to work, the left-hand side of the expression needs
to have parentheses in it. For example:

s/(.)(.)(.)(.)(.)(.)(.)/$1$2$3-$4$5$6$7/

should do the trick for you.

The following:

s/(...)(....)/$1-$2/

does the same thing (effectively), but is shorter and easier to write.

s/abc1234/abc-1234/ would do it, as would $_ = "abc-1234", but since
you've given only one example and no rules, it's hard to generalize
that.
