Q: Why doesn't the uses work how it should work.
A: When calling OnUses the ScriptEngine.OnUses is called. SYSTEM uses is always 
   called, even with no OnUses. You can add variables, types, classes or functions 
   there or your could attach a script to it.   

Q: How can I add a variable to the variable list:
A: The prefered way to do it is in the OnUses function:
  function MyOnUses(id: Pointer; Sender: TIfPasScript; Name: string): TIfPasScriptError
  begin
    if Name='SYSTEM' then begin
	  Sender.AddVariable('Edit1Text', 'String', False)^.CV_Str := Edit1.Text;
      RegisterStdLib(Sender); // This function adds the standard libraries.
      MyOnUses := ENoError;
    end else 
      MyOnUses := EUnknownIdentifier;
  end;
  After the TIfPasScript.Create, you do: script.OnUses := MyOnUses;

Q: How can I read the value of a variable:
A: First call GetVariable('VarName'), if the result of
  that function is nil, the variable does not exist. Else if it does
  exist, the function returns returns an PIFVariant.

Q: Can you help me with ....? Are you going to add .....?
