Main Features of ISPF Purpose of ISPF

The Interactive SystemProductivity Facility, or ISPF, isa development tool set for thez/OS operating system. It hasbeen used since 1975 toincrease the productivity of thedevelopment of mainframeapplications, because it

provides an extensive set ofprogrammer oriented facilities.

Main Features of ISPF Customizing ISPF Dialogs

A programmer can use ISPFto produce custom dialogs

and applications. Suchdialogs run on a traditionalIBM user terminal, like the3270, or a terminal emulator

running in a window on aPC.A dialog receives requestsand data from a user, then

responds by using ISPFservices to obtaininformation from, or enterinformation into, the z/OS

system.

Main Features of ISPF Four Major Components of ISPF

ISPF includes four majorcomponents:

Dialog Manager (DM)

Program Development Facility

(PDF)

Software Configuration andLibrary Manager (SCLM)

Client/Server (C/S)

Main Features of ISPF Dialog ManagerThe Dialog Manager controls theinteraction of a dialog's

elements, and provides otherservices to dialogs during theirexecution. ISPF can issuerequests to display panels and

format screens. ISPF can storeinput, create output, process,and verify data. You can evenuse ISPF as a simple data

management system.

The Dialog Manager (DM)

provides services and dialogs,including:

display and variableservices

input and output user and application

profiles

table management

system interface services dialog testing and

debugging aids

Main Features of ISPF SCLM

Software Configuration and Library Manager (SCLM) supportsthe development of complex software applications. It helps

developers to track and update the components of a softwareproject from the design phase to release of the final product.

The project manager defines the architecture for yourapplication, relating all important components. SCLM ensuresthat the architecture definitions are followed by controlling andautomating updates of related components.

Main Features of ISPF The ISPF SCLM Functions

SCLM provides library andconfiguration management

capabilities such as: Tracking how all the pieces of anapplication fit together

Calling the necessary compilers,

assemblers, or other translators Promoting application componentsthrough the different stages of thedevelopment cycle, and linkageeditors

Auditing changes to thecomponents

Saving versions of the componentsas they are updated

Main Features of ISPF Client/Server (C/S)

The Client/Server (C/S) part of ISPF allows you to run ISPF on programmableworkstations and PCs under Microsoft Windows or UNIX.

You can display panels using thedisplay function of theworkstation operating system. Forexample, on a workstation

running Microsoft Windows,panels are rendered possessingthe look and feel of all typicalwindows.

The core component of ISPF,which facilitates this, is called theWorkstation Agent (WSA).
