MOTCLE	ABBREVIATION	DESCRIPTION
GDG		See generation data group
GDG		generation data group
GDG		Generation Data Group. Collection of (z/OS non-VSAM) datasets (see GDS) all with the same logical name (GDG Base Entry) the individual datasets are uniquely identified by the generation number which is stored as part of the dataset name. The datasets can be referenced either by the explicit generation number or the relative generation number. GDGs are useful where datasets are cycled ? standard JCL can be used without having to change the dataset names for each run.
GDS		(1) See general data stream (2) See Global Directory Service (3) See generalized data stream (4) See generation data set
GDS		Generation DataSet. One of the datasets in a GDG.
generation data group	GDG	A chronological collection of historically related data sets that do not use the Virtual Storage Access Method (VSAM) each data set is called a generation data set. See also generation data set
generation data group	GDG	A collection of historically related non-VSAM data sets that are arranged in chronological order each data set is called a generation data set
generation data group	GDG	groupe de fichiers class?s par ordre chronologique
Generation Data Group	GDG	Generation Data Group is a group of related files that can be referenced individually or as a group. The files within a GDG are assigned names derived from the name of the GDG base. The individual files within a group have a generation number added to the end of the name to make each file name uique. For example, if the GDG base is called PROD.WORKFILE.TEMP then the first file created within the GDG will be given the name PROD.WORKFILE.TEMP.G0001V00. Subsequent files are then named by incrementing the generation number resulting in filenames ending in G0002V00 through G9999V00. Once the G9999V00 is reached the numbering will start again from G0001V00. The two zeroes on the end of the name are used to represent a volume number that is used when the file is stored on media requiring the use of multiple volumes. For more information describing GDG usage with programming examples refer to http://www.simotime.com/gdgone01.h
generation data group base entry		An entry that permits a data set that does not use the Virtual Storage Access Method (VSAM) to be associated as a generation data set (GDS) with other data sets not using VSAM
generation data set	GDS	One of the data sets in a generation data group (GDG) a GDS is historically related to the other data sets in the group. See also generation data group
generation number		The number of a generation within a generation data group (GDG). A zero represents the current generation of the group, a negative integer (-1) represents an older generation, and a positive integer (+1) represents a new generation that has not yet been cataloged. See also GDS reclaim processing
pseudo-generation data group		A collection of data sets, using the same data-set name pattern, that are managed like a generation data group
