<[[Brennen]]> Sad as this is to admit, I always forget what a Perl for-loop is supposed to look like, probably since I mostly just use "foreach" to iterate over lists.

Anyway, it goes like this:

 for ($i=1; $i < 100; $i++) {
    # ^init ^while    ^increment or whatever
   print "Number $i\n";
 }

<[[alan]]> if mem usage doesn't matter you can always just do

 for my $i (1..99) {
  ...
 }

but then again, if you meet a C programmer on the street and you don't remember the first form, he may just punch you in the nuts. that could be bad.
