Re: Re: Undef doesnt work?This has got me stumped

Thanks for the reply. I understand the package variable bit, thanks, but when (or how) does this get destroyed? Does the package reference survive until the script dies?

Correct, package variables live until perl exits, or the variable is explicitly destroyed. If you want shorter lived variables then you'll want to be using lexical variables who's life-span is tied to the length of the surrounding lexical scope (unless they're referenced from a higher scope). For more information on lexical variables see. Lexical scoping like a fox. HTH `_________ broquaint`	[reply]
