1 A Modern Programmers Tool Set: CODE OCEAN Technical Conference Catch the Wave Susan M. Gantner Partner400 partner400.com Your partner in AS/400 and iseries Education One of IBM's best-kept software secrets has hit the big time! Now that CODE is included in WDT/400, which is available with all development systems as of V5R1, CODE an essential tool that every AS/400 shops can afford. After all "free" is a pretty good price! CODE is a complete Windows-based programming environment for AS/400-iSeries programmers. It replaces PDM, SEU, SDA, RLU, and the various flavors of source view debuggers. It also adds its own unique features, such as a local code verifier that works even when you are not connected to your AS/400. You can develop and maintain your host-based green-screen applications much faster with CODE and enjoy it more! It supports all the most popular AS/400 languages, both ILE and Original Program Model (OPM) versions. Not only that but it also supports editing of Java and HTML code.once you try it you will soon wonder how you ever coded without it! We'll demonstrate for you some of our favorite features in CODE/400, so you can see for yourself what it can do for you. The author, Susan Gantner, is co-founder of Partner400, a firm specializing in customized education and mentoring services for AS/400 and iseries developers. After a 15 year career with IBM, including several years at the Rochester and Toronto laboratories, Susan is now devoted to educating developers on techniques and technologies to extend and modernize their applications and development environments. This is done via on-site custom classes as well as conferences and user group events. Together with her partner, Jon Paris, Susan authors regular technical articles for the IBM publication, eserver Magazine, iseries edition, and the companion electronic newsletter, iseries Extra.

2 What is CODE? A part of Websphere Development Studio (WDS/400) A complete application development environment for developing AS/400 host applications on your Windows PC Formerly called "CODE/400" CoOperative Development Environment An integrated set of development tools that provides significant productivity enhancements for: The edit/compile cycle Designing DDS screens and reports Debugging AS/400 applications And best of all it's "Free" CODE Tools CODE Editor A powerful PC editor for AS/400 and PC source code CODE Designer A rich graphical interface for designing/maintaining DDS display, printer and database files CODE Debugger Debug host applications from your workstation CODE Project Organizer PDM for your PC - integrates and organizes your programming projects Copyright Partner400, CODE400 Introduction - Page 3-4

3 Why CODE? Significant productivity gains New functions and GUI Shortens edit/compile/debug cycle Off-loads host cycles Use PC for editing, designing and verifying code Work in 'disconnected' mode - perfect for telecommuters Investment protection Works equally well with leading edge and legacy languages Even non-ile code! Migration path Working together with the other tools in WDT/400, create applications for host, client and web environments How we work without CODE Open source 2- Make changes 3- Save source Submit compile 5- Batch job ends 6- Completion message Look for spool file 8- Find errors 9- Locate errors in source Copyright Partner400, CODE400 Introduction - Page 5-6

4 How we work with CODE 1- Open Source 2- Make changes 3- Verify - Error feedback immediate and obvious 4-Submit compile - Auto save to host - Error feedback when compile ends An Integrated Environment Project Organizer Editor Debugger Program Verifier Error List Program Generator Designer Windows 98 Windows NT/2000/XP Host execution Copyright Partner400, CODE400 Introduction - Page 7-8

10 Graphical Compare Inserted Lines Deleted lines Editor Programming Why program it? Need for a new editor function Repetitive task, fastpath key for heavily used function Tailor the editing environment for your shop What can you do? Specify editor default settings Add editor functions and your own macros to the menus and toolbar Assign/re-assign keys and/or line commands to editor functions and your own macros Interact with the host via the CODESRV command How do you do it? Write macros in REXX or Java + editor commands IBM supply a number of samples - more in a moment Use the 'profiles' to load in the macros. Copyright Partner400, CODE400 Introduction - Page 19-20

18 What About the New WDSC Package? Websphere Development Studio Client New packaging which replaces WDT/400 in V5R2 and late shipped versions of V5R1 The good news: Great new Java programming toolset, new web design tools, strategic "Eclipse" plug-in technology base The bad news: CODE functionality is not yet incorporated into Eclipse base Existing CODE tool is shipped with WDSC... HOWEVER... It is NOT separately installable (you must install everything) Help text integration is not nearly as good as in existing (V5R1) CODE tool The moral is: If you ONLY want CODE tools, don't lose the V5R1 WDT/400 CD set!!! CODE Summary Complete development environment on your Workstation Huge productivity boost! Work disconnected from host - Great for telecommuters Offloads AS/400 programmer workload Packaged with 4 other great workstation-based programmer tools: VisualAge RPG VisualAge for Java for iseries Websphere Studio for iseries Webfacing Visit IBM's web site: User newsgroups Downloadable presentations and lab exercises Fix pack downloads News, FAQs, etc. Copyright Partner400, CODE400 Introduction - Page 35-36
