VerQueryValue from Win32Api can return a pointer to a structure called VAR.

Var {
    WORD  wLength;
    WORD  wValueLength;
    WORD  wType;
    WCHAR szKey[];
    WORD  Padding[];
    DWORD Value[];
};

In the open array Value[] Windows returns the supported Languages and CodePages of the file.

How can I get this information under Delphi 2.01? Or how can I rebuild this structure in Pascal.

Value is an array of DWORD's.

I've no access to Delphi here, but this should be how to go:
--//--
var
  P: Pointer;
  v: DWORD;
begin
  P := VarQueryValue(...);
  v := VAR(P)^.Value[0]; // now v holds first element of Value
end;
--//--

HTH.
