WA1944 COBOL Intermediate Workshop Training and Courseware

The course starts with an overview COBOL for z/OS and many of the differences from previous version of COBOL including the callable functions. An overview of the Language Environment / 370 (LE/370) is presented along with how some of its features can benefit the COBOL for z/OS programmer.Extensive workshop sessions utilize many of the COBOL for z/OS features that are different from previous COBOL environments.  The LE/370 features are also used in workshop sessions.

Student skills are refined for the areas of sequential file processing, program looping, conditional program statements, and table processing.  Both external design documentation and internal program documentation are stressed as the key to building more maintainable, more understandable, and more reliable programs.  The causes of program dumps are discussed along with solutions to the most common causes of program dumps.  A program dump is reviewed in detail.

Objectives

As a result of the class, the student will be able to:

• discuss the major differences between COBOL for z/OS and previous versions of COBOL
• discuss the importance and benefits of the LE/370 environment
• code and debug programs using many COBOL for z/OS features
• code and debug programs using several LE/370 features
• code and debug programs using common COBOL features such as  sequential file processing, program looping, conditional program statements, and table processing
• provide both external design and internal program documentation
• analyze a program dump and correct the program.

Audience

The course is for students who have used COBOL for z/OS and LE/370 and need to refine their skills and explore more of the features of COBOL for z/OS and LE/370.

Prerequisites

•  Six months experience with TSO/ISPF is required.
•  Six months experience with COBOL coding or successfully completion of a course in COBOL for z/OS is required.
