You could do this:

$string = sprintf("%4s-%4s", $string);

or this:

$string = join('-', (split($string))[0..4], (split($string))[0..4]);

Neither of these is a correct solution. The first will print the entire string followed by a dash, then four spaces. The second will try to split `$_` using `$string` as a regex. We're not really tightening our belts, it just feels that way because we're getting fatter.	[reply] [d/l] [select]

Oh, right. Oops. `my $string = "ABCDEFGH"; my @string = split //, $string; $final = (join "", @string[0..3])."-".(join "", @string[4..7]); print $final; # if my code is right, this is "ABCD-EFGH"` [download]	[reply] [d/l]

If you're going to do that you might as well do #!/usr/bin/perl @list = split //, 'ABCDEFGH'; s&&local$/; <DATA>&e&&y&; &&d;& s#zoTfFdDsOt##g; while/(\D)(\d+)/gi; sub z{(&O-&O)((&O-&O)(&O-&O))} sub o{&z-((&O-&O)*(&O-&O))+&O-&O} sub T{&z-(&O-&O)} sub f{&T+(&O-&O)} sub F{(&O-(&O-&O))/(&O-&O)} sub d{print chr shift} sub D(@){map chr,@_} sub s{print D$1->(@list[split//,$2])} sub O{ord shift} sub t{&z+&O-&O(A)} __DATA__ #t50703010o507040703002o507040703004o507040703003F01020f5070 306057t50703050t50703060o507040703003T50703010T50703040o5070 40703005F01020t50703070T50703040o507040703005t50703030F01020 T50703010f5070306057T50703060t50703020T50703040o507040703005 [download] Proves the same point!
