Not exactly. At least not on my Perl installation [5.6.1 on W2K]. open returns 1 on success, but does not return a value on failure. #!/usr/bin/perl -w use strict; use warnings; my $value = open FILE, "values.txm"; # doesn't exist. print "Value is " . $value . "\n"; #line 9 referenced below my $line = <FILE>; Produces: Use of uninitialized value in concatenation (.) or string at E:\d_drive\perlStuf f\guests\post_if.pl line 9. Value is OTOH, if I correct the filename my $value = open FILE, "values.txt"; I get Value is 1 from the same line.
