XRef data is retrieved with functions of the Natural LIST
XREF
command.
Functions provided by the Natural LIST XREF
command can be grouped into three groups:
Functions retrieving information on specific types of members (for example programs or data areas). All functions from Invoked programs through Report programs with xref data in the XRef Menu are of this type. See Retrieving Information for Individual Members.
Functions retrieving information on the consistency of an application as a whole. The functions are called from a submenu that is called with code A (Verify application). See Verifying the Integrity of an Application.
Functions that are used to manage sets. Sets allow efficient use of information retrieved from XRef data. See Using Sets.
