In the absence of code that demonstrates the problem, it is hard to move forward. A simplistic test of the problem as described shows that the join works fine: [0]{} Perl> print async{ `perl -e1`; return 'Completed'; }->join;; Completed [0]{} Perl> [download] The backticks ran in a void context, running an executable that produced no output; the thread ended returning the string 'Completed'; which was retrieved with join, and passed to print and displayed. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". I knew I was on the right track :) In the absence of evidence, opinion is indistinguishable from prejudice.	[reply] [d/l]

Completed
