Audience This is an introductory course for new users of

the z/OS operating system.

Prerequisites The student should have a basic

understanding of computer systems.


3/21



OverviewThis course, z/OS Introduction to ISPF, introduces you to

the z/OS Interactive System Productivity Facility (ISPF) withspecial emphasis on the Program Development Facility(PDF). It begins by describing the menu system throughwhich you access ISPF starting with the ISPF PrimaryOptions Menu. You will learn ways to navigate and jumpthroughout the system and use interesting features such as

split-screen. The course also covers the fundamentals ofmanipulating data sets, including browsing, viewing, andallocating.

The ISPF editor facility is covered in detail including

inserting, repeating, copying, moving, and deleting lines. Youwill learn to customize the environment through edit modesand the creation of edit profiles. Advanced techniques likefinding and changing text, excluding and redisplaying lines,as well as shifting text is described.


4/21



OverviewA thorough foundation in the ISPF utilities is provided.

This includes the library utilities, data set utilities,move/copy utility, data set list utility, and

compare/search utilities.

The final topic covers the processing of background

jobs. It explains the phases of a background job. You

will learn to submit a job for background processing,

monitor the status of a job while it is waiting, executing,

or waiting for its output to print, and how to retrieve the

output for a job that is completed.


5/21



ObjectivesUpon completion of this course, you should be able to:

Describe the purpose of ISPF and its relationship to TSO

Effectively navigate throughout ISPF and describe its menustructure in detail

Describe the nature of sequential and partitioned data sets, how

they are named, created and allocatedView and browse data sets

Utilize the ISPF edit facility, import primary commands and linecommands

Insert, delete, copy, move, repeat, exclude, redisplay, and shift linesChange and maintain edit profiles

Search for and change data


6/21



Objectives

Utilize the main functions of the library utility, data set utility, move/copyutility, data set list utility, and compare/search utility

Mark data set members with various options using member selectionlists

Allocate new data sets using an appropriate block size for the DASDdevice

Display data sets across the entire system or across an individualvolume

Describe the phases involved in the life of a background job

Use the ISPF Batch Selection Panel to create multiple jobs steps for

language processingUse the OUTLIST Utility and SDSF to display job status anddisplay/print job output

Primary Functions

The Interactive SystemProductivity Facility (ISPF)is a robust development

tool set for the z/OSoperating system. It hasbeen used since 1975 toincrease the productivity ofthe development of host-based applications,because it provides anextensive set ofprogrammer orientedfacilities.


10/21



Primary Functions

The Time Sharing Option (TSO)is IBM's mainframe time-sharingoperating system, which alsohas a long and rich heritage.

ISPF can be seen as anextension to TSO. It is housed"under" TSO, and sometimesthe acronym TSO/ISPF is usedto describe the facility providedby these closely associated

subsystems. The servicesprovided by ISPF complementthose of the host TSO system toprovide interactive processing.

Primary Functions


13/21



Primary Functions

ISPF contains four major

components:

Dialog Manager (DM)

Program Development Facility(PDF)

Software Configuration Library

Manager (SCLM)

Client/Server (C/S)


14/21



Primary FunctionsThe Dialog Manager (DM)

The Dialog Manager (DM) provides services and dialogs to

end users, including:

display and variable services

input and output

user and application profiles

table management

system interface services

dialog testing and debugging aids

other services


15/21



Primary FunctionsProgram Development Facility (PDF)

The Program Development Facility (PDF) provides services to

assist the developer of applications and dialogs. It contains:

a hierarchical library that contains numerous productivity-enhancing functions

services that include

dataset and catalog utilities

edit and browse functions

TSO command interfaces

data set search and compare functions


16/21



Primary Functions

Software Configuration Library Manager (SCLM)

The Software Configuration Library Manager (SCLM) is a library

facility that supports projects in developing complex software

applications by providing software configuration and librarymanagement support.

It supports the software development cycle from the product

design phase to the release of the final product.


17/21



Primary Functions

Client/Server (C/S)

The Client/Server (C/S) part of ISPF provides the ability to run ISPF

on programmable workstations and PCs under Microsoft Windows.

You can display panels using the display function of the workstation

operating system.


18/21



Primary Functions

The Dialog Manager controlsthe interaction of a dialog'selements, and provides otherservices to dialogs during theirexecution. ISPF can issue

requests for panels to bedisplayed and for screens to beformatted. ISPF can store input,create output, process andverify data. You can even useISPF as a simple datamanagement system.

A list of dialog managementservices provided by ISPF isshown here.


19/21



Primary Functions

The SCLM is an installable option ofISPF that supports the developmentof complex software applications byproviding software configurationand library management functionsfrom the design phase to release ofthe final product.

You define architecture for yourapplication relating all importantcomponents. The SCLM ensuresthat the architecture is followed bycontrolling and tracking the process.It enhances software quality andimproves programmer productivity.

Some of the services the SCLMprovides are shown on the right.


20/21



Primary Functions The Client/Server component of ISPF enables you to run ISPF on a

programmable workstation. Panels are displayed using the displayfunction of the workstation operating system.

For example, on a workstation running Microsoft Windows, panels are

rendered possessing the look and feel of all typical windows.

The core component of ISPF, which facilitates this, is called the

Workstation Agent (WSA). ISPF WSA is supported on:

Microsoft WindowsAIX

HP-UX

Sun OS

Unit 1 summary

In this module, ISPF Functions, you learned

ISPF facilitates the work of programmers and end users by providinglabeled fill-in-the-blank screens, called panels.

The screens are arranged in a simple two-level menu structure.
