use strict;
my $drive = "a";
my $path = ":\\path\\to\\file.xxx";
foreach (0..25)
{
print "$drive$path\n";
$drive++;
}
since incrementing a string in perl is possible. Forget about looking at
strings like an array :)
Also, Perl style likes foreach() over for() usually.
If you want to do it in a really perly way:
print $drive++."$path\n" foreach (0..25);

check out perldoc perlfunc -- there's a whole section on built in string
functions
to get the length of a string use length (surprised?)
my $sString = "foo bar";
print length($sString)."\n";
