Method: Instructor led, Hands-on workshops

Price: $2950.00

Course Code: MF2025

Audience

Programmers, technical support personnel, and any others that have a need to develop ISPF/DMS dialogs.

Description

This course introduces students to the skills necessary to use ISPF Dialog Management Services in a z/OS environment. The students learn how to create the required user dialog libraries and implement DMS dialogs.

Students will learn advanced techniques of ISPF Dialog Management Services (DMS)

A series of written and lab exercises will be used to reinforce the classroom education.

Objectives

Upon successful completion of this course, the student will be able to:

Dialog panels.
Help panels.
Dialog functions using REXX or CLIST.
Customized error messages.
Customized menus.
File tailoring skeletons.
ISPF Library Management Services
Use the ISPF Dialog Test Facility.
Create and process DMS tables (temporary and permanent).
Invoke Dialog Management Services from PL/1, COBOL, and FORTRAN programs.
A series of written and lab exercises will be used to reinforce the classroom education.
