The RPG Dude - Episode 1 - Design
- 1. www.looksoftware.comwww.looksoftware.com The RPG Dude Take a seat while the meeting is starting…
- 2. www.looksoftware.comwww.looksoftware.com The RPG Dude His Design perspective
- 3. www.looksoftware.comwww.looksoftware.com RPG preamble • To display data, the RPG uses display formats • Display formats are described within DDS (Data Description Specifications) • The formats in DDS contains: • Field buffer definition • UI description (position, DDS keyword…)
- 4. www.looksoftware.comwww.looksoftware.com RPG preamble • For the RPG, a format is only a Field buffer definition that can be read or written, the RPG doesn’t care about any UI description. • This is the workstation 5250 that monitors all UI description, • with OA, we could decide to monitor them or even to ignore them. Then we could use DDS formats only for Field buffer definition. And use RPGOA only to send and receive these buffer.
- 5. www.looksoftware.comwww.looksoftware.com RPG preamble In RPG you can write many formats. Write format5 Write format4 Write format3 Write format2 Write format1 But in 5250 you only see what is filtered by the workstation 5250.
- 6. www.looksoftware.comwww.looksoftware.com RPG preamble With OA they could all be available. Write format5 Write format4 Write format3 Write format2 Write format1 Remember the iceberg ? 5250 is the tip, OA is the whole
- 7. www.looksoftware.comwww.looksoftware.com RPG preamble And the UI could decide to show formats data fields through any UI components, and all in the same form.
- 8. www.looksoftware.comwww.looksoftware.com RPG preamble With OA many formats can be exchanged between the RPG and the UI, in 1 transaction. Many RPG/DDS formats 1 RPG Many UI components 1 form 1 I/O
- 9. www.looksoftware.comwww.looksoftware.com Now, let’s talk about The RPG Dude - and particularly about His Design perspective
- 10. www.looksoftware.comwww.looksoftware.com The RPG Dude He is under pressure… So many app to maintain and to develop…
- 11. www.looksoftware.comwww.looksoftware.com The RPG Dude Here is his boss…
- 12. www.looksoftware.comwww.looksoftware.com The RPG Dude Here is the customer…
- 13. www.looksoftware.comwww.looksoftware.com The RPG Dude Our dude has to design new screens… What are his tools ?
- 14. www.looksoftware.comwww.looksoftware.com The RPG Dude SDA ? Screen Design Aid ? Aid ??
- 15. www.looksoftware.comwww.looksoftware.com The RPG Dude RDi ? SDA in eclipse ? Aid ??
- 16. www.looksoftware.comwww.looksoftware.com The RPG Dude Aid ?? No drag&drop ? No UI Controls ? No Widgets ? No GUI properties ? No “What You See Is What You Get” ? nope…What You Get Is What You See
- 17. www.looksoftware.comwww.looksoftware.com The RPG Dude This is not going to make our customer happy…
- 18. www.looksoftware.comwww.looksoftware.com The RPG Dude Our dude tries hard any possible way to design new screens… SDA, RDi, third party tool…
- 19. www.looksoftware.comwww.looksoftware.com The RPG Dude Results are not what he was expecting… The pressure increases…
- 20. www.looksoftware.comwww.looksoftware.com The RPG Dude Must our dude end up like a bunny ?
- 21. www.looksoftware.comwww.looksoftware.com The RPG Dude A condemned bunny ?…
- 23. www.looksoftware.comwww.looksoftware.com The RPG Dude That cannot be it… A possibility HAS TO EXIST !
- 24. www.looksoftware.comwww.looksoftware.com The RPG Dude A new solution ? A new paradigm ? In the industry they call it looksoftware
- 25. www.looksoftware.comwww.looksoftware.com The RPG Dude looksoftware IDE Rich Designer, drag&drop, GUI controls, widgets, a full IDE! You can build new Form with rich components for mobile, browser or desktop.
- 26. www.looksoftware.comwww.looksoftware.com The RPG Dude looksoftware IDE Save Form and generate XML-DDS Save Form and generate XML-DDS & RPG
- 27. www.looksoftware.comwww.looksoftware.com The RPG Dude looksoftware IDE Save Form and generate XML-DDS <xml> <format name=‘fmt01’> <field name=‘fld01’ length=‘10’ type=‘A’/> <field name=‘fld02’ length=‘12’ type=‘A’/> <field name=‘fld03’ length=‘5’ type=‘S’/> </format> <format name=‘fmt02’> <field name=‘fld04’ length=‘12’ type=‘A’/> <field name=‘fld05’ length=‘5’ type=‘S’/> </format> … Data field descriptions are represented in XML, simply grouped by <format>. This XML is the Open Access Metadata Open Standard (OAMOS) www.IBMiOA.com
- 28. www.looksoftware.comwww.looksoftware.com The RPG Dude looksoftware IDE Save Form and generate XML-DDS DDS A R fmt01 A fld01 10 H A fld02 12 H A fld03 5 0 H A R fmt02 A fld04 12 H A fld05 5 0 H … With the XML, a DDS is automatically generated, no DDS keywords needed, no positioning, no limits. (Only for grid, we use 4 DDS keywords mandatory for SFL but that’s it!)
- 29. www.looksoftware.comwww.looksoftware.com The RPG Dude looksoftware IDE Save Form and generate XML-DDS RPG fld01 = ’abc’; fld02 = ’xyz’; fld03 = ’123’; write fmt01; fld04 = ’qwe’; fld05 = ’rty’; write fmt02; … read fmt01; (1st read triggers I/O to GUI) read fmt02; … An RPG is also generated, it can be used as a Unit-test for your form I/O or as a base for your business logic. RPG can then simply control any data fields or GUI attributes
- 30. www.looksoftware.comwww.looksoftware.com The RPG Dude looksoftware IDE Design time: Runtime: Designer XML DDS RPGOA RPGOA XML UI RPG compilation with OA OA handler - openlook OA handler - openlookAnd all will work with other RPG or 5250 or system displays.
- 31. www.looksoftware.comwww.looksoftware.com The RPG Dude looksoftware IDE Then our Dude can create a new Rich Form with the Designer, save it, and control it directly in RPG. 1 Designer, 1 RPG, 1 Dude. Save Form and generate XML-DDS & RPG
- 32. www.looksoftware.comwww.looksoftware.com The RPG Dude looksoftware IDE IDE ? Insert Dude Empowerment
