Actually - it does matter where I print it! Moving it outside the loop makes it work correctly - thanks. I didn't know, and still don't, how that makes a difference!	[reply]

Consider a very simple loop like this: `my @a; for (qw/a b c/) { push @a, $_; print (join ', ', @a), "\n"; }` [download] In the first iteration, @a contains a, so the output is `a` [download] In the second iteration, @a contains `a, b`, so the total output is `a # output from previous iteration a, b # output from current iteration` [download] In the third iteration it will print `a, b, c`, so you'll see a total of three `a` in the output - probably the duplicates you complained about. If you move the print out of the loop, you just get `a, b, c` because that's what `@a` contains. Perl 6 - second systems done right	[reply] [d/l] [select]
