Here is one way - say you want to replace 'baz' with 'qux':
use strict; my @array = qw(foo bar bazzle baz); @array = map { s/^baz$/qux/;$_ } @array;
This will replace all occurances of 'baz' in the array however. You didn't specify if this is okay or not.

UPDATE: oops - yet another problem to not solve with map. Thanks for the tip grantm and Anony. :)

So ... let's say that you only wanted to replace the first occurrance of 'baz':
my @array = qw(foo bazzle baz baz); for (@array) { last if s/^baz$/qux/; }
much better, just don't try this with a list:
for (qw(foo bazzle baz baz)) { last if s/^baz$/qux/; }
which will not work, because you are trying to modify read-only values.
