Why do you want another way? For most situations lexical variables declared with my are exactly what you want. There are also "global" variables that are declared with our or (subtly diffent iirc) with `use vars ($variables)`. You could also say `no strict 'vars';`, but that's a really bad idea unless you know what you're doing.	[reply] [d/l] [select]

You may want to look up what this is good for: Use strict and warnings	[reply]

Alexseki as an aside, you might want to give the perlsyn documentation module a look, specifically search for 'Declarations', so you don't run into trouble with lexical variable scoping issues. Pancho	[reply]

Proper way for working with variables is to declare them first. There are other options like `our` ~~or `local`~~. Are you averse to variable declaration? Perl doesn't force you to declare the variables you work with if you do not use strictures and warnings, but who wants that?	[reply] [d/l] [select]

local doesn't declare a variable.	[reply]
