I know this is really dumb and basic but I can't figure it out.
What it is is really unnecessary. This is what arrays are for. Would you care to explain why you don't want to use an array? 
#!/usr/bin/perl -w

use strict;

my @string = qw/Jessy Bob Nancy/;
my $num = 0;
while ( $num < @string ) {
    print "$string[$num] ";
    $num++;
}

### or, instead of a loop, just:

print "\n@string\n";

update: If the reason for not using an array is that the numeric index can be really large (meaning it can be a very sparse "array"), then this is what hashes are for -- just use the numeric as the hash key instead of as an array index.
