If substr's okay, how about this kind of thing: `my $string = "This is a very long string"; foreach (0..length($string)) { if(substr($string, $_, 1) eq " ") { # Replace this position (space) with a "\|" substr($string, $_, 1, "\|"); } } print $string;` [download] It kinda depends on what you're trying to do, but I think this might help. (Note that you can also replace with the empty string). Hope it does. jarich Update: forgot the length. ;)	[reply] [d/l]

A reasonable solution, but I want to do this without invoking the regex engine When you say, "I wanna do $X", and the answer is "by doing $Y", and then you say "I wanna do $X but without doing $Y", you are obligated to provide a reason why the best/easiest way ($Y) is so easily dismissed. How close to doing $Y can you get, for example, and why not $Y? {grin} You haven't yet. Please do so. -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.

What's the deal with imposing ridiculous, artificial restrictions? Split is the correct way to do it, so there. -- Regards, Helgi Briem helgi AT decode DOT is	[reply]
