Access the next occurrence of an argument in a TStringList

[TRon]

Which seems to contradict FreePascal's documentation in this case:

According to Delphi's wiki documentation the indexof with offset neither exists for TStringlist nor TStrings :shrugs:

That is correct, but that is not the issue.  I did a test in Delphi where a base class has public overloaded virtual methods, a derived class that overrides only 1 of them, and then call both overloads via a pointer to the derived class:

Code: Pascal  [Select][+][-]

1. type
2.   TTestBase = class
3.   public
4.     procedure DoIt(AValue: Integer); overload; virtual;
5.     procedure DoIt(AValue1, AValue2: Integer); overload; virtual;
6.   end;
7.  
8.   TTest = class(TTestBase)
9.   public
10.     procedure DoIt(AValue: Integer); override;
11.   end;
12.  
13. ...
14.  
15. var
16.   t: TTest;
17.  
18. t := TTest.Create;
19. t.DoIt(1);
20. t.DoIt(2, 2);
21. t.Free;

It works fine in Delphi without needing to type-cast to the base class.

The same test should work in FreePascal as well (ie, calling both IndexOf() overloads on a TStringList object without type-casting to TStrings).  If it doesn't work, then it should be reported as a compiler bug.
