In this instance, the "\*" basically returns a pointer to the filehandle. Something to do with typeglobs, an area I haven't explored much (yet). The asterisk indicates the typeglob (I believe), and the backslash performs it's usual "return-a-reference-to-this" function.
A typeglob is basically a complete symbol table entry, but you can use them (and references to them) like file handles. Hot Pastrami In reply to Re: Re: Re: Why the error?
