Break
Exit current loop construct.
Declaration
Source position: system.fpd line 35
procedure Break;
Description
Break jumps to the statement following the end of the current repetitive statement. The code between the Break call and the end of the repetitive statement is skipped. The condition of the repetitive statement is NOT evaluated.
This can be used with For, var{repeat} and While statements.
Note that although Break is a compiler intrinsic (i.e. is treated specially) it is defined as a procedure in the system unit, and hence can be redefined.
Errors
None.

If I>5 Then
Break;
Writeln (i);
end;
I:=0;
Repeat
Inc(I);
If I>5 Then
Break;
Writeln (i);
Until I>=10;
For I:=1 to 10 do
begin
If I>5 Then
Break;
Writeln (i);
end;
