I'm assuming that you mean
@array = qw(ball bat helmet)
Also, I'm assuming that this is homework.
Here's a hint: while(@array) tests the current length of the array. That means you will get an endless loop, but only if the array never changes.
You may want to take a look at perlfunc's section "Functions for real @ARRAYS"
updated: removed commas from qw() list. thanks liverpole.
