By-Reference : Prodataset

Hi All,

     I am using prodataset in my project using By-referto share same copy of prodataset.

   But I stuck one place, I lost rerefence of datast in called program.

   I found these line in prodataset pdf

    " You can only specify BY-REFERENCE on an internal procedure or user-defined function call, not on a RUN of an external procedure. When you pass a

     ProDataSet parameter by reference, the called routine’s ProDataSet definition is bound to the calling routine’s ProDataSet only for the duration of the call. "

   " Any reference to the ProDataSet, except where it is passed in from another routine BY-REFERENCE, results in a runtime error."

  Please suggest me any way to persist, the reference of  dataset in called program.

Thanks.
