PACBASE Fundamentals

What is PACBASE ?

PACBASE is a tool for generating COBOL programs

Developed by CGI Systems Proprietary tool of IBM

PACBASE - Features Standard and structured code Version control Reusability Control Break Processing File Matching Report Generation

PACBASE – Terms Repository Library Entity

Repository

Repository is the physical storage All the entities of pacbase are

stored in repository It is accessed by all the users of

the system

Library

Library is the logical division of Repository

To provide access only to a group of users on a particular division

Ensures security

EntitiesBasic units of managing information Elements Segments Programs Reports Macros

Elements Elements are lower level entities Corresponds to an elementary

item defined in COBOL program Eg: 01 EMPNO PIC X(005) can be

defined as an element in pacbase

Segments Group of elements form a Segment Corresponds to a group item defined

in COBOL program Eg: 01 EMPREC. 05 EMPNO PIC X(005). 05 ENAME PIC X(025). can be defined as a segment in

pacbase

Programs & Reports

Program – entity where all the inputs for generating a COBOL program are defined

Report - entity where all the inputs for generating a report in a COBOL program are defined

Reusability & Cross Reference Entities once created are available to all

users Reusability – Using the already available

entities Cross-Reference – List of entities using

a particular entity (element, segment, report or macro)

Version Control

Achieved by three types of sessions Historic session – can only be viewed cannot be updated Test session – can be updated Current session

Starting PACBASE Type pacbase in the first screen. Give login id and password Give PB35 which is the transaction id for
