I use this class for similar approaches. The class wil automatically create the properties for you.

_screen.AddProperty('memo',CreateObject('parameterX'))
_screen.memo.xx=10
_screen.memo.yy='Some text'
?_screen.memo.yy
?_screen.memo.xx

define class ParameterX as custom
  function This_Access(tcMember)
    if type('This.' + tcMember) = 'U'
      This.AddProperty(tcMember)
    endif
    return This
  EndFunc 
  function AddVar(tcMember,tcData)
      AddProperty(this,tcMember,tcData)
    return This
  endfunc
EndDefine
