Data set naming conventions

In addition to the rules, there are naming conventions, specifically conventions that define a data set to ISPF/PDF. These conventions are an offshoot of the rules and provide standards that make it easier to use TSO/E whether in ISPF/PDF or in line mode TSO/E. Thus a data set name that follows the data set naming rules does not necessarily follow the conventions.

The conventions are:

Both sequential and partitioned data set names consist of three qualifiers.
PROJECT, the first qualifier, is your prefix as specified by the PROFILE command. Sometimes your prefix is your TSO/E user ID.
GROUP, the second qualifier, can be any meaningful name.
TYPE, the third qualifier, is a description of the type of information in the data set such as data, text, or the name of a programming language.

An ISPF/PDF data set with a member might be named as follows:

PROJECT   ===> prefix
GROUP     ===> memo
TYPE      ===> text
MEMBER    ===> feb27
