Unpack is even faster, for fixed-format strings.

Do u have to examine
Try this:
$string =~ /^.{3}\d\s[^\s]+\s([a-zA-Z]+)\d+$/;
$prefix = $1;
That should match:
- any three characters at the beginning of the string: ^.{3}
- followed by a number: \d
- followed by whitespace: \s
- followed by any one or more characters until the next whitespace [^\s]+
-
Something like this :
/(\w\s){2}([a-zA-Z]+)\d*/

Paul,
Give this a shot:
/^\w+\s+\w+\s+([A-Za-z]+)\d+/
A regex should be as explicit and exclusive as possible, so I would
remove the lowercase (a-z) portion of the character class if you know
for sure that the letters you want will always be uppercase.
