you should use something like 

trap "SIGINT" { block_to_do (some, stuff)}

^C in unix sends SIGINT , tipically.

You could even try 
at_exit { endBlock }
 
In this way you'll have endBlock anyway.
I suppose that trap SIGINT won't work in dos, but you
could do something like this to check if the program
actually ended or had been interrupted

#start
<your code>
#good end
$ended=TRUE


at_exit {
unless $ended
 <interrupted, exception..>
end
}
