Remarks

The DSOINSTANCE event allows you to supply a DataSet instance programmatically. For example, if you create a DataSet that contains look-up information, like code tables, and you store the DataSet handle globally so multiple forms can use it, you can supply that DataSet to a form in the DSOINSTANCE event. Since an additional form will be using the DataSet, you must increment the reference count for the DataSet using the DSMethod DS_ADDRESS$ or the DataSet will be destroyed when the form is destroyed. If you supply the DataSet, then return 0 from the event handler.
