Question

I have the following code in a Delphi 2007 application:

function TBaseCriteriaObject.RecursiveCount(
  ObjType: TBaseCriteriaObjectClass): integer;
var    
  CurObj: TBaseCriteriaObject;
begin
  result := 0;
{$WARNINGS OFF}
  for CurObj in RecursiveChildren(ObjType) do
    Inc(Result);
{$WARNINGS ON}
end;

Which produces this warning:

[DCC Warning] BaseCriteriaObject.pas(255): H2077 Value assigned to 'CurObj' never used

I understand the warning but don’t want to change the code, so how do I get rid of the warning because {$WARNINGS OFF} does not seem to work in this case?

Answer 1

From Delphi Help:

The $WARNINGS directive only works at
the procedure or function level
granularity. That is, you can surround
entire procedures and functions with
the $WARNINGS directive, but not
blocks of statements within a
procedure or function.
