Abstract

A generalized data set comparison is performed which determines whether entries in one list are present in another list. Control statements are utilized by which the user can define the algorithms used to match the lists, and to describe follow-up actions which can be taken. Examples of the use of such a dataset comparison include the following: a) Confirmation that PDS members in one dataset are found in another (where the index of the PDS is captured as a list) b) Confirmation that PDS members are represented in list of data found in a sequential file c) Creation of lists of matching elements d) Creation of lists of non-matching elements e) Creation of auxiliary files containing data related to the matches or non-matches between the lists
