Re: Re: Question about warn statement

...but then $x is still undefined outside the do{} block (which may or may not be a problem).

my $x;
open (FILE, ">temp") || do {
   warn "error message";
   $x = 1;
}
print "\$x is $x";

You're right but (as you mentioned) the fact that `$x` is undefined may not be a problem at all. `my $x; open (FILE, ">temp") \|\| do { warn "error message"; $x = 1; }; if ($x) { # so something }` [download] -- vek --	[reply] [d/l] [select]
