I use an object to store all my variables.

oStorage=CreateObject('parameterX')
oStorage.nVar1=10
oStorage.lVar1=.T.
oStorage.cVar1='aaa'
oStorage..cVar2='hello'
?oStoage.nVar1

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
