RE: Hash of arrays

[mark crowe (JIC)]

You've got caught in the old = vs == trap. A single = sign sets the variable
on the left to equal that on the right, while == tests for equality. So in
your case

        $testsec{'AB'}[$i] = "6543" 

sets $testsec{'AB'}[$i] to "6543", and then returns 'true' (yes, I have
successfully set that variable). What you want is:

        if ($testsec{'AB'}[$i] == "6543") {# then do stuff}

We've all got caught out by this one (probably quite regularly).
