Program test;

procedure doit(z:longint);

try
y := 100;
x := y div z;
finally
writeln('in the finally block now');
end;
end;
begin
doit(0);
writeln('if you''re right you will see this');
end;
The program will terminate in the finally block and you will never see the
final writeln "if you're right you will see this');
There are two conditions under which finally is entered...
1) Normally... the code is executed and the program continues.
2) Exception... the code is executed and the program terminates.
