My Parameterx class automatically adds the necessary Addproperty() line if you set a property which does not exist.

*How to use the class:
Public oData
oData=CreateObject('parameterX')
oData.MyVar1=1
oData.MyVar2='some text'
?oData.Myvar1

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
