IBM VisualAge Pacbase is a code-switching structured programming language that is developed and maintained by IBM. VisualAge Pacbase runs on both IBM and non-IBM mainframes and integrates with IBM WebSphere Studio Application Developer. When compiling Pacbase code it is first translated into COBOL and then compiled to binary.

1. 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

7. Repository & Libraries

9. 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

39. Ending PACBASE Session
 Press Pause Break
 Enter OFF
