in reply to Re: fork, %SIG, END.
in thread fork, %SIG, END.


it is my understanding that the program does not exit within the END block, but after the END block has completed; the scope returns to a global (file) one, where $? is then returned, like so:
END { local $?; # preserve previous return code # do anything } # now, outside of the END block, # $? refers to the global and the # program officially terminates # using this value.

    I agree with that code block and think we are speaking towards the same thing. I use the local $? in my END block to preserve the exit code also.

    I think I brought it up as an heads up because that bit me in the butt when I first started using the END block, I wasn't preserving the $? and therefore code inside the END block was causing it to be modified and the script not exiting with the value I wanted.
