Jacek Laskowski indeed. That has been the Delphi build path since about 20 years.
ReplyDeleteNo ,it's not a bug , because length is used as a macro for constant , and as a pure function for variable.
ReplyDeleteThe same applies for "sizeof",except its a pure macro.
eg:
var
Str: string;
L, sz: Integer;
begin
Str := '123';
L := Length(Str);
L := Length('123');
Length('123'); // Error.
sz := sizeof(Str);
sizeof(Str); // Error.
end;
This works fine too, so the context must be more confined:
ReplyDeleteunit Unit1;
interface
implementation
procedure Foo();
begin
length)(
end;
end.
