Need Help??

in reply to Can you create *real* global variables?

There are 2 ways I have seen to do this. One, 5.6 and higher, is to start the name with a ^. Blame Dominus for this hack. The other one is to start the name with a '.

In both cases the variable is always kept in package main. And both syntaxes will not be supported in Perl 6.

Except that starting a variable name with a `'` is just a hack for starting it with a `::`, which doesn't stop me from then appending a different namespace. The `^` hack is totally separate. _____________________________________________________ Jeff`[japhy]`Pinyan: Perl, regex, and perl hacker. `s++=END;++y(;-P)}y js++=;shajsj<++y(p-q)}?print:??;`	[reply]

I just said what would work, not why it does. You might also have noted that I did not say why each solution was going to not be supported in 6.0. I have to leave people some incentive to re-read the documentation! :-)	[reply]
