Creating the reference data set

A reference data set can be created when you display the reference list or refer to a reference member for the first time via the EFind command. If the current reference data set does not exist, the following panel will be displayed.

You can overtype the reference data set name to choose an alternative name.

Note: The allocate dialog should be used to allocate the reference data set to ensure it is defined with the correct file attributes. When allocating a new reference data set, you will be subsequently placed in an edit session of a member called DEFAULT; in this session, you can specify the resources you want the product to search by default. For more information, see How the data set or resource list is determined.
