WDSc & RSE for RPGers

The SEU and PDM of the Future

Susan Gantnersusan.gantner @ Partner400.comwww.Partner400.com

WebSphere Development Studio client for iSeries - WDSc to its friends - is the Eclipse-based workbench from IBM. Don't let that "WebSphere" word worry you. There are many tools in this toolset which have nothing to do with WebSphere or with development for the web. The best news of all is that if you're on V5R1 or later, you probably already have WDSc available to you at no extra charge! In this session we will concentrate on the specific tools that are targeted to RPG programmers - tools to replace SEU and PDM, for example. We'll look at Remote Systems Explorer (RSE) for iSeries and the jLPEX editor and its related tools. Join Susan for an in-depth look at why the WDSc toolset can (and should!) change the way you do your iSeries development in the future. After all - you have nothing to lose but your application backlog!

Unlike PDM, WDSc filters are retainedAnd multiple filters can be open at one time

Project-based, team-sharable developmentWorkbench plug-ins are supplied for CVSiSeries vendors such as Aldon, MKS, and Soft Landing are also "plugged-in"

Remote System Explorer

Double Click on the tab to make it full-screen

Prompting with F4

Prompting is less necessary because of

intelligent Format Lines and Tab key

Any Window can be made a "Fast View"

This makes it easily accessible from full screen editor mode

V5.1.2 includes cross reference info in Outline!

V6: Dock on Left, Bottom or Right - Orientation

Code CompletionTired of forgetting subprocedure, subroutine and field names?

Start to type then press Ctrl + Space Bar to see a list of matching items

Use the cursor keys to highlight the item you want and Enter key to select itOr key additional characters to shorten list

Prototyped calls show the parameters required to invoke them


Local Code Verify

Cached (local copy) of external file

descriptions and /Copy automatically

Verify runs built-in copy of compiler checking.Failed compiles need

never happen!

Tip: ALWAYS verify locally before submitting a compile.

positioned to that line in the editor


Hardware RequirementsWorkstation

WDSc Workbench requires a large workstationMinimum Pentium III 800 Mhz (higher recommended)Minimum 768 MB memory, 1 GB recommendedMinimum disk space: 11 GB, including installation & development objects

Monitor requirements1024 x 768, 256 colors requiredDue to the nature of the workbench, 17" or larger monitor is recommended

For installationDVD drive is recommended, unless installing from a network driveMultiple CDs required, making installation more slow and cumbersomeUpdates to the workbench are typically done via the internet

Broadband connection required for satisfactory response timeUpdates can be downloaded to a network drive and installed from network

If you don't have the recommended workstation, don't despair!CODE editor works beautifully on a MUCH smaller system

Minimum Pentium II 600 Mhz, 256 MB memory, 700 MB diskV5.1.2+ allows separate install of CODE without the WDSc workbench

V6 requires a second separate install process for CODE/VARPG

New with V6.0.1 Technology Preview of "WDSc Lite"

WDSc Lite is a slimmed down workbench with only the:Eclipse workbench (branded asRational Software Development Platform)Remote System ExploreriSeries ProjectsiSeries Integrated Debugger

Requires only 256 MB RAM to run However, more memory is currently required to get it installed!

Optional installation feature for 6.0.1

Must already have full WDSc 6.0.1 installedFirst update to 6.0.1 electronically from V6.0 (if necessary)

Use new Rational Product Updater interfaceFrom Start > Programs or from Help > Software Updates in workbench

After 6.0.1 installed via "Updates" tab, use "Optional Features" tabCreates a second copy of the workbench Fully supported technology previewAfter Technology Preview stage, hopefully it will be installed separately


Here's What to Install on Your WS

Tips for New WS Toolset UsersNever close a source member to open another one

Multiple open members open at a time - a powerful feature

Never close a source member to save it or to compile itSave and/or compile without closing

After all, what are the chances you're really finished ?

Verify before compilingMuch faster, especially if caching ... which reminds me ...

Always, always cache file descriptions & Copy membersVerify in seconds (or less) rather than a minute or soAs of V5.1+, caching is turned on by default in WDSc workbench


SummaryWDSc & CODE offer very powerful features

But they do require an investment of time to learn themThe documentation is not the best in the world - but it is getting better

Once you have learned the basics your productivity will riseAnd keep rising and rising and .....

Make sure you understand how caching worksThe real speed benefits are gained by caching file descriptions etc.
