Actually, the element of the array Does exist, as I printed out from the hash in the code above the segment I posted. I tried not to post too much code, since the rest worked. Using $tlist$tnum$i = $threads{$thread}$i; as you suggested, I still got a null instead of a number printed. Then I replaced the loop with the push you recommended, and got the syntax error: "Type of arg 1 to push must be array (not array element)at that line number near "]" " Accordingly I then replaced the $tlist$tnum with the array @tlist, and then got the syntax error "syntax error", without further comment.
