Re: is filehandler used ?

Ok, here is the situation, if the filehander is used, I would like to use it

if ( OUT ) {
    print OUT " bla bla\n" ;
}
[download]

unfortunately, if ( OUT ) is always true!!
Hopefully this makes sense

any idea of the diff between yours and mine? I've always used HANDLE: `use strict; use warnings; open(OUT, ">test.txt") or die "Can't open file to write, $!."; if(defined fileno OUT){ print "File handle is valid."; }else{ print "Nope."; } close OUT;` [download]	[reply] [d/l]

No diff. `\*HANDLE` also works.	[reply] [d/l]
