The following example shows a DATASET-HANDLE parameter.

For this parameter, ProxyGen generates the following method in the proxy:

For INPUT and INPUT-OUTPUT parameters, the .NET client code must supply an instance of a strongly typed DataSet or an instance of the System.Data.DataSet object that contains the appropriate schema and data, as well as any required ABL-specific mappings. For OUTPUT parameters, the DataSet variable must be declared, but the instance is created by ABL and returned to the .NET client as a parameter with all the necessary ABL mappings. For more information on these mappings, see ABL ProDataSet to ADO.NET DataSet mappings.
