He Brian,
In Perl, you don't have to declare your variables if you don't want to.
You are building the count hash on the fly here. All you are doing is
incrementing itself by one everytime the word is found.
@words=('test','this','that','test');
for $word (@words) {
$count{$word}=$count{$wor
e hash to lookup the value it is storing for
the key called $key.
Hope this is clear and of some use. Good luck learning Perl.
John
