I've recently just implemented OO error handling using Error.pm. I've been implementing code which throws errors if something fails of the form:- 
#$HashOfTNBs{$rec_count}{$subindex} = $1 or throw TNBCriticalColExcept
+ion("Cannot add multiple key entry in hash array");

The problem is that when $1 = 0 it throws the error - rightly so.

However even when I bracket the assignment the same happens.

How can I check whether a statement executes successfully without having to wrap it in a mod and create a return code and then check it.

I'm sure there is a simple one liner way of doing this but I cant quite get the syntax right.

tks
