John,
In the form's Init:

lparameter toparam
local llretval
llretval = .T.

if vartype(toparam) = 'O' then
   THISFORM.oParam = toParam
else
   * parameter object wasn't passed correctly so don't instantiate the form
   llretval = .F.
endif

With THISFORM
   if llretval then
      * param object passed corectly so set the values for form controls
      .text1.Value = .oParam.uVarOldValue
      .Caption = .oParam.cCaption
   endif
Endwith

return llretval

If the parameter object isn't passed then the Init will return .F.. The form will not instantiate.

Then in the Click method, you can access the form's oParam property. You can set the form up to have an oParam property from the Form Designer or you can add an AddProperty call in the Init method (it's up to you).

HTH.
