Symbolic references Can't Post

I would appreciate it if anyone could give me an idiots guide to symbolic references. I understand Hard ref's but symbolic ones just wont fit in my little brain. Ive read explanations in the best known Perl books and all the doc's available on the subject but none are simple enough for me.

If possible could you include information on dereferencing (and maybe how the symbol table fits into the equation).

I know its a hell of alot to ask, but until i thoroughly understand this i cant fully understand the debugging concept of "use strict 'refs'".

TIA

The book "Advanced Perl Programming" has a very good section on hard and symbolic references.

I think any book on Perl with "advanced" in the title probably wont work for me Kev, but thanks anyway.

It will, the concepts might be advanced but the explanations are easy to understand and have many examples and even illustrations (explaining how the symbol table works for example).

If you already understand hard references, symbolic references should be pretty easy to understand.

Looks like there's a pretty good discussion about this topic going on on Perl Monks.
