for a := 0 to x do
for b := 0 to y do
for c := 0 to z do
if (...) then
begin
// Do something and then exit all loops
exit; // Or maybe: goto OutSideOfLoops;
end;
In Pascal I can't change the 'a' and 'b' values to force the end of
the loop. So what other GOOD option do I have but to use exit or goto?
Use a while or repeat loop. The whole point of a for-loop is exactly
to have the compiler ensure (to the best of its abilities) that you do
not accidentally modify the loop variables.
Well, if you think an exit is ugly, image changing this code into while
loops. May as well use assembly.
OT: The only things I dislike about pascal is that the value of a
variable at the end of a for loop is undefined. It should remain at the
value it had when exiting the loop.
