But both are the result of an oversimplification!
outer: loop
inner: loop
Complex_Actions_1;
if First_Condition then
Some_Justify_Actions;
goto next_outer;
end if;
Complex_Actions_2;
if Second_Condition then
Some_Other_Justify_Actions;
goto next_outer;
end if;
Complex_Actions_3;
end loop inner;
Complex_End_Statments;
exit outer when Other_Condition;
More_Statments;
<<next_outer>> null;
end loop outer;
I'd like to find a more amazing version of this braindead goto.
Please do not assume, that I'm too stupid to invert a condition in a
simplified example. IT'S NOT HOMEWORK!
