1.2.3 Using Data Sets
A data set is a unit of information that can be stored and retrieved.
Some types of data you might put into a data set are:
- A program's source code
- Job control language statements
- Input to a program
- Output from a program
- Memos
- CLIST statements
- Text of a report
A data set is organized in one of several arrangements and is described by
control information that the system can access. The two types of data sets
most often used with TSO/E are:
- Sequential data set - A single unit with data arranged in a sequence,
from top to bottom or beginning to end.
- Partitioned data set (PDS) - Subdivided unit that is divided into
separately named, independent partitions called members, each of which
can contain data. A partitioned data set has a directory that contains
information about each member.
