PACBASE Fundamentals

2.
What is PACBASE ?
 PACBASE is a tool for generating
COBOL programs
 Developed by CGI Systems
 Proprietary tool of IBM

3.
PACBASE - Features
 Standard and structured code
 Version control
 Reusability
 Control Break Processing
 File Matching
 Report Generation

4.
PACBASE – Terms
 Repository
 Library
 Entity

5.
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

6.
Library
 Library is the logical division of
Repository
 To provide access only to a
group of users on a particular
division
 Ensures security

Entities
Basic units of managing information
 Elements
 Segments
 Programs
 Reports
 Macros

10.
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

11.
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

12.
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

13.
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)

14.
Version Control
Achieved by three types of sessions
 Historic session – can only be viewed
cannot be updated
 Test session – can be updated
 Current session

15.
Starting PACBASE
 Type pacbase in the first screen.
 Give login id and password
 Give PB35 which is the transaction id for
pacbase
 Give pacbase loginid, password and
library name
 Main Menu appears

Main Menu

21.
Accessing Menus
 H or PF5 – Main Menu
 Each entity is identified by unique
1-character entity type code
E – Element S – Segment
P – Program R – Report
 H followed by the entity code – Entity
Menu Eg: HP – Menu of Program
Screens

22.
Program Menu

23.
Definition and General
Document Screens
 Definition Screen
- Entity Code followed by Entity Name
Eg: Ppppppp – Program Definition Screen
 General Document Screen
- by giving G
Eg: EeeeeeG – Element General
Documentation Screen

24.
Definition Menu

25.
Gen. Doc Menu

26.
Call Screens
 To call an entity within another
 Using C followed by entity code
 Eg:CD – Call of data Structures
CE – Call of data Elements
CP – Call of Macros
SddssCE – Segment call of Elements

27.
Call of Data Structures

28.
Work Areas Screen

29.
Cross Reference Screens
 Cross Reference Screen
- by using X followed by the entity
code
Eg: EeeeeeXP{ppppppP ff sf lll}
Element X-Reference to Program
pppppp starting with procedural
code ff sf lll

30.
Cross Reference Screen

31.
Segment Choices
 SddssLSP – List of parent segments
 SddssLSC – List of Child segments
 SddssLAL – Level Address Length
 SddssDED – Data Element Details
 SddssSTA – Statistics

32.
Segment Description

33.
Special Choices
 Enter LC followed by the entity code
Eg: LCPppp*
List by Programs starting with ppp
 LH – List of historical frozen
sessions
 LL – List of locked entities
 JP – Jump Previous

34.
Special Choices – Contd
 JF – jump forward
 N*lib – new library
 NHssss – new session
 NH9999 – return from historical
session to current session
 WS – word search
