: That what I'd say also except here I'm using a series of numbers for(100..1000) { }
: Each one has the same string except the number is different
: And then want to just declare them all with one call and use them as I want.

You have to turn off strict 'refs'.
use strict;
# ...
for ( @list ) {
no strict 'refs';
# ...
}

show you how it's done.
