Return value of function xyz might be undefined
<![CDATA[
Question:
I seem to be getting a bogus warning about an undefined function result. Can anyone confirm this?
Answer:
Both Delphi 5 and Delphi 6 will report:
Return value of function Undefined2 might be undefined
Delphi 7 will complain about Undefined1 as well.
Return value of function Undefined1 might be undefined
Return value of function Undefined2 might be undefined
This is a bug in Delphi 7.
program Project1;
function Undefined1 : boolean;
var
b: boolean;
begin { Undefined1 }
Undefined1 := False;
b := True;
if b then
Undefined1 := True
end; { Undefined1 }
function Undefined2 : boolean;
var
b: boolean;
begin { Undefined2 }
b := True;
if b then
Undefined2 := True
end; { Undefined2 }
begin
end.
