7.2.1 Accessing the System
Since LOGON to TSO/E is dependent on the telecommunications access method
used with TSO/E, the System Standards implemented by the Systems
Programmer, and the related program products installed, you should reference

7.2.2 Entering and Manipulating Data
In ICCF, data is entered and stored as a member of an ICCF library. Data is
restricted to 80 byte records in an ICCF library. You may enter data into an ICCF
library member from Input, Edit, or Full Screen Edit mode. ICCF allows
modification of data stored in members of ICCF libraries only. Modifications are
made while in Edit or Full Screen Edit modes and physically change the data on
the DTSFILE.

In TSO/E, data is entered and stored in sequential data sets, or partitioned data
sets (PDS) using the Interactive System Productivity Facility/Program
Development Facility (ISPF/PDF) editor or the TSO/E EDIT command and its
subcommands. Most users use ISPF/PDF, rather than the older TSO/E EDIT
command, to gain increased usability and improve their productivity. Record
formats may be either fixed or variable with a logical record size less than or
equal to 255 and a block size less than or equal to track length. A PDS is a data
set partitioned into one or more independent groups called members. Each
member must have a unique name and can be referred to separately by
appending the member name, enclosed in parentheses, to the data set name.

The name you give a data set should follow the TSO/E naming conventions. A
TSO/E data set name normally has three fields.

Identification Qualifier - This is always the leftmost qualifier of the full data set
name. For TSO/E, this qualifier is the prefix selected in the PROFILE command. If
no prefix has been selected, your user ID will be used.
