Re^2: fork, %SIG, END.

etm1777:

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.
