COBOL for Experienced Programmers

This five-day course has been specifically designed for programmers with experience in other languages (PL/I, Assembler, Java etc.). It is taught using a combination of classroom tuition and practical exercises, and includes realistic case studies that can be based on the client's particular environment and work-load.
This course is available publicly on demand and also for one-company, on-site presentations.

Prior knowledge

Prerequisite for attendance is experience in programming skills in other languages. Attendees should also have a conceptual level understanding of the z/OS mainframe environment and the ability to use TSO/ISPF and JCL.

Delegates will learn how to

  • code the four divisions of a COBOL program
  • write, compile and test COBOL batch programs in an IBM environment
  • access files from COBOL programs
  • perform arithmetic operations in COBOL programs
  • use conditional expressions
  • call COBOL subroutines
  • define and access tables using both subscripts and indexes.

Outline

Structure & coding conventions
PC Metalanguage; the COBOL character set ; coding conventions; divisions, sections, paragraphs, sentences and statements

IDENTIFICATION DIVISION

ENVIRONMENT DIVISION

DATA DIVISION
FILE SECTION and WORKING - STORAGE SECTION; FDs; hierarchy and level numbers; elementary and group data items; PICTUREs; the VALUE clause; editing characters; literals, figurative constants.

PROCEDURE DIVISION
MOVE, ADD, SUBTRACT, MULTIPLY, DIVIDE and COMPUTE; PERFORM; ACCEPT and DISPLAY; OPEN and CLOSE; READ and WRITE; file access modes; indexed and relative files.

Conditional statements and branching
IF and ELSE; comparisons and tests; Level 88; negated conditions; nested IFs; GO TO; PERFORM UNTIL; EVALUATE.
 
Table handling and data representation
Tables; PERFORM...VARYING; implicit and explicit redefinition; DISPLAY, COMP, COMP-3, SYNC and JUSTIFY; data representation; INITIALIZE.
 
Additional statements and alternative constructs
