Thanks Plamen but I don't use DE in my apps. My fault but perhaps I should of been much clearer from the start. I needed to "programmatically" determine the Parameters of a SP. I found my answer, just issue "Refresh" method of the Command object. Thanks again.

>Use Data Environment. Add connection to the database. Then add command to this connection and in its Properties specify to SP as data source. Then on the "Parameters" tab you will see all parameters along with returned result, if it exist.
