A Look at Eclipse IDE for OS 2200-
What is an IDE
• My definition:
– An Integrated Development Environment is a single
application that includes many of the tools necessary to
develop an application, and which automates many of the
common tasks in that development.
• Generally includes
– Code Editors
– Builders
– Debuggers
• Often includes
– Deployment assistants
– Administration tools
– Configuration tools

History of Eclipse
• Eclipse is the foundation of the WebSphere IDE
(now called Rational Application Developer)
• IBM donated Eclipse to the Open Source community
• The Eclipse foundation was established to govern its
distribution
• IBM remains heavily invested

Eclipse Structure

Our Philosophy of Development
• OS 2200 Development is based on the work file.
– The connection to the 2200 is configured.
– A 2200 project is associated with a program file on a 2200
– The project’s editable files stay on the 2200.
• Editing is done in Eclipse IDE to the 2200 files.
– CIFS provides connection to the 2200.
– Editing is done in Eclipse IDE the 2200 elements are
changed. No copy is kept on the workbench.
• Builds are user written
• Builds are carried out by a Telnet session.

What you get
Galileo (Eclipse 3.5) JEE Release
A full featured IDE for building enterprise n-tiered Java applications for J2EE platforms. The
IDE is comprised of Eclipse and a set of recommended and tested Eclipse plug-ins. Unisys
extends the IDE with the Unisys Telnet Plug-in, an Eclipse & Plug-in Install Guide, and a
tested Application Development Guide; providing everything needed to build and deploy Java
applications to J2EE systems, including the OS2200.
UNISYS offering for 12.1
Unisys Composite Application (CA) Plug-in
The Eclipse Composite Application (CA) Plug-in simplifies the creation of Java composite
applications that use OS2200 COBOL, C , and Fortran programs. This collection of plug-ins
extends Eclipse with an OS2200 project framework and language editors, and allows users to
create, modify, build , debug, and integrate OS2200 3GL programs with new or existing Java
application programs.
Unisys Java Application Integrator (JAI) Plug-in
The Java Application Integrator (JAI) is a collection of Eclipse plug-ins tailored to developers
who uses Java connection classes to integrate Java applications with OS2200 databases
(DMS, RDMS, BIS), transactions (TIP/HVTIP), and programs. It simplifies the process of
creating, configuring, using and deploying the resource connectors for integrating Java
applications with OS2200 resources

Setting up Eclipse IDE for OS 2200-
High level overview
• Latest version available at the Unisys FTP support site:
– ftp://ftp.support.unisys.com/pub/2200/ide/
• Go to the folder of your choice (probably the latest level)
– Download one called “all-in-one”.
– Extract this file to a folder.
• For debugging you will also need the file
Eclipse2200padslib.zip
– Have a drive mapped to os2200 share on host
– Unzip it. It expands to the folder “eclipse2200”
– Copy this folder to the mapped drive

The Demo Part
• Create a COBOL data access program
• Write and test the SQL
• Use amazing and powerful tools for COBOL
• Build the project the push of a button
• Debug the output
• Explore the data base from Eclipse IDE for OS 2200
• Add the DB code rapidly to the program.

The Demo Part-
The Telnet Client
• Bring up Eclipse
• Open a Telnet Session
• Look at CIFS (show the shares)

– Page 2: Build Script and Brkpt files
– Page 3: Picking project elements

Creation and Update

The Editors
• C editor
• Fortran Editor
• Plus Editor
• Java Editor
• Text Editor
• COBOL Editor

COBOL-Editor
• Keyword Colors
• Auto-completion
– Templates for:
• Divisions
• Procedures
• Functions
• Entire operations
• Column sensitivity without restrictions

COBOL-Editor

The Build
• Simple stream to complex SSG
• User determined
• Compiler errors are harvested and presented in the
Problem view, in the project, and in the editor.
• An End line summary view shows the build line that start
“END”

UCS Debugging-
Setup
• Make sure you compile with debug options
• Debug setup page
• Special link

UCS Debugging-
Setup

Debugging –
Procedure
• Standard debugging
– Step over
– Step into
– Step out
– Set breakpoints
– Resume
• Display variables
• Change variables

Data Explorer-
Basics from Connection
• Connect
• Expand connection
• Do sample data
• SQL editor
– Add table
– Add select items
– Add conditions

Data Explorer-
Sample Contents of an RDMS Table

Data Explorer-
Using the SQL Editor

Exotic Programming.-
More Ways to improve Productivity
• Specialty Templates
– RDMS query
– RDMS Data
• Paste in the query
– Format for COBOL
– Do some editing
• Add the data names
– Split the screen
– Add the” into” clause
• Build and run

Using Templates-
Imported Templates for Specialties

The Split Screen

Conclusions –
The Blessed End is Near
• Even in the hands of a rank amateur, Eclipse IDE for OS
2200 can make COBOL programming for the OS 2200
productive.
• Eclipse can be customized for your shop.
• We continue to add productivity enhancements to Eclipse
and the Editor
