So you need a really old book as your reference :-/
(I trust you have a dog-eared copy of the blue camel.)
If you haven't yet, you should bookmark
https://perldoc.perl.org/5.8.8/index-language.html (or 5.8.4 or whatever it
is) at work.

(Uri's advice from the Perldoc that it isn't even a good idea to delete
from an Array on a modern perl is well-taken also, but as Randal points
out, doesn't affect your legacy perl.)

So you'll need to code this another way.
Uri's suggested *splice*() was indeed available in 5.8.x -- but was
upgraded in 5.14. and later, so rely on the old documentation
<https://perldoc.perl.org/5.8.8//functions/splice.html>, as latest docs may
advise on corner-cases wrongly.
