\n should work from *NIX boxen. Not sure about m$, but I think it still
works there.

lufthans@fs:~$ cat /tmp/carl.pl 
#!/usr/bin/perl

$fred ="anke
georg
uwe";
print "<$fred>\n";

@fred = split( '\n', $fred );
foreach $entry ( @fred ) {
        print "<$entry>\n";
}

$fred =~ s/\n/<here be newlines>/g;
print "<$fred>\n";
lufthans@fs:~$ /tmp/carl.pl 
<anke
georg
uwe>
<anke>
<georg>
<uwe>
<anke<here be newlines>georg<here be newlines>uwe>

Sorry, don't feel like doing cgi :). Potential probs when coming from cgi is
that you're getting something other than \n.

Don't forget to look for control chars as well.

ciao,
