Greetings, I am learning how to use the Parallel:loop module and have had an error in tempfile(). I am running the below (very simple) perl script. It will work. I run the exact same thing again - it doesn't work. I run the exact same thing again - it works. I change it a bit - it works/doesn't work. = intermittent. The exact error message is in the attached jpeg screen shot of my command prompt. I am running strawberry perl that I downloaded a few months ago on windows 10. Best, Teal _______________________script_______________________________ use Parallel::Loops; my @num = 1 .. 50; my $pl = Parallel::Loops->new(5); my %out; $pl->share(\%out); $pl->foreach( \@num, sub { my $num = $_; # note this uses $_, not @_ $out{$num} = $num ** 2; }); foreach (sort keys %out) {print "$_ : $out{$_}\n";} ********************************************************** Electronic Mail is not secure, may not be read every day, and should not be used for urgent or sensitive issues

Additionally, it will spit out this error WHILE the script is running (I tried it on a large dataset). Show quoted text

The line in question simply does: use File::Temp(); .... my ($fh, $filename) = tempfile(); I have no idea why you get permission denied errors creating temporary files in the C:\Users\WILLIA~1\AppData\Local\Temp folder. Are you the WILLIA~1 user? If so, are there funky permissions in that directory? I'm sorry, but Parallel Loops needs to be able to create temporary files on systems that don't have a reliable select() call such as yours. You can try setting $ENV{TMPDIR} to a directory where you *know* you have the proper rights to write temporary files. Peter
