Routines for Managing Groups of Objects
GRP provides facilities for handling groups of objects which can be described by character strings (e.g. file names, astronomical objects, numerical values, etc). Facilities are provided for storing and retrieving such character strings within groups, and for passing groups of character strings between applications by means of a text file. It also allows the creation of groups in which each element is a modified version of an element in another group.
