Description |
The Break procedure forces a jump out of the setof statements within a loop. Like the Goto statement, it should be used with caution.
The next statement that is executed is the one following the loop terminator. For example:
for i := 1 to 10 do
begin
...
break;
...
end;
size := 10; // breaks to here
It is important to note that the Break statement only jumps out of the current loop - not out of any nested loops above it. The Goto statement can.

Example code : Breaking out of a loop for good reason | var
i : Integer;
s : string;
begin
s := '';
 // A big loop
for i := 1 to 10 do
begin
s := s + IntToStr(i) + ' ';
 // Exit loop when a certain condition is met
if Random(4) = 2 then Break;
end;
ShowMessage('i = '+IntToStr(i));
ShowMessage('s = '+s);
end;
