Hi tobyink,
Thank you for replying. You, Neighbour, and the other Monks really helped me out. But I wanted to ask you how should I close the filehandle $fh after it has been opened?
I've written my code somewhat similar to you and Neighbours but I am not sure if it is correct. Here is a snippet of the problem:
sub my_close {
my( $fh ) = @_;
+
close($fh) or die "$!\n";
}
+
sub my_open {
+
my( $file, $mode ) = @_;
+
open my $fh, $mode, $file or die "$!\n";
+
return $fh;
}
sub errors {
+
my( $file, $mode ) = @_;
my $fh = my_open($file, $mode);
my @errors = ();
while( <$fh> ) {
chomp;
+
next if /^[a-z]/;
push( @errors, qq(Line $. '$_' does not begin with lowercase l
+etter.) );
}
my_close($fh); # Safe to close file like this???
+
+
return @errors;
}
Thank you.
