It obviously works, but I don't see *how*. > there is no package variables in Perl, only global or lexical. local doesn't work on what you refer to as package or my-variable. it works on the stack. all variables are on the stack whether it's global or lexical (there are different stack for different thing of course). local localizes the variable(puts it on the stack), the value is pop off the stack after the block exit(no matter how it exit) so the original value is retain. that's *how* :-) david david -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
