Re^4: Problem with internet explorer.Mozilla firefox,beonex,netscape ok.

Just to help the newbies, when you call a function just with &foo the values in @_ are used as arguments to the function. This leads to some weird results.

So, when you just want to call a function, use foo().

Erm, yes and no. `&foo;` (with no parens) passes the caller's `@_`, whereas `&foo();` (with empty parens) passes an empty argument list. The former also has the side-effect of ignoring any prototypes. See `perldoc perlsub` for more details.	[reply] [d/l] [select]
