2. [TLK-1431] Our Real-World Cases of AI-Driven Development in IBM i + RPG - May the Bob be with us Takashi Fujinuma Senior Manager, IGUAZU Corporation Atlanta, GA October 26–29 Tuesday, Oct 27 3:00 PM - 3:20 PM EDT
3. I'd like to talk about 01 Our challenge 02 AI-driven development process 03 May the Bob be with us IBM TechXchange | © 2026 IBM Corporation
4. Who am I? Takashi Fujinuma Bio: 2026, IBM Champion 2025, joined the technology preview of Project Bob Guitarist 2024, participated in the public preview of watsonx Code Assistant for i 2018, developed a meeting minutes summarization solution (Watson Speech to Text) 1991, infrastructure engineer for IBM i (AS/400) IBM TechXchange | © 2026 IBM Corporation 4
5. Our challenge: AI-driven RPG development using IBM Bob IGUAZU is a Value Added Distributor of IBM hardware, software, and services Alpha Communications, our group company, has long focused on RPG development Now, we're renewing our information portal with IBM Bob IBM i × RPG × Python IBM TechXchange | © 2026 IBM Corporation
6. Renewing Information Portal Site: Project in Progress IGUAZU Enterprise System Landscape Web system(Python) Sales Management System(RPG on IBM i ) Installed Base Management Quote/Order Subsystem Quote Request Management Order and Delivery Management Shipping/Sales Subsystem Procurement Subsystem Order Subsystem AR, Billing, and Collections Subsystem Accounts Payable and Payment Subsystem Inventory Subsystem Accounting System IBM TechXchange | © 2026 IBM Corporation EDI
7. AI-driven development process Powered by Premium Package for i IBM i RPG Source Download Directly RPG source code is stored locally. C:/ 1. AGENTS.md Created by Bob from Alpha Development Standards.txt - Always Loaded 2. SKILL.md Created by Bob from Alpha Development Standards.txt - Called only when coding Compile Automatically 3. workspace folder (/workspace_root) Bob created locally 4. Storing RPG sources in text Bob downloads to the workspace folder. No copy-and-paste or file transfer needed! IBM TechXchange | © 2026 IBM Corporation 7
8. Generate source 5x speed Compile Using this RPG as a reference, please create a new RPG named TST011 that adds update logic Do not use Japanese in the comments — please write them in alphanumeric characters only. Japanese comments exceeded the fixedlength field, causing compile errors. IBM TechXchange | © 2026 IBM Corporation 8
9. Bob picked the right skill on its own I’m using my SKILL.md & AGENTS.md properly. IBM TechXchange | © 2026 IBM Corporation 9
10. Bob compiled it on IBM i by itself Leave it to me. 350 lines of code · 6.5 Bobcoins IBM TechXchange | © 2026 IBM Corporation 10
11. What about Python? (40 .md Files) Guide Lines I will follow your instructions IBM i table IO rules.md IBM i table IO seq rules.md IBM i table naming rules.md Backend-guide.md(Python// FastAPI / DB2 on AS/400) common-components-design.md error-handling-guide.md process-management-rules.md . . . . . .

12. UPDATE: AGENTS.md now lives on IBM i New slash command /init in Premium Package for i Until now AGENTS.md on the PC Local workspace folder Created from Alpha Development Standards.txt (see slide 6) Now: /init QSYS: the AGENTS.MD member of the BOBSRC source file IFS: .bob/AGENTS.md Guidelines stored in either place are loaded automatically into IBM i Developer mode and Database mode. QSYS workspace {currentLibrary}/QBOBSRC/AGENTS.MD IFS workspace {ifsWorkingDirectory}/.bob/AGENTS.md Auto-injected into IBM i Developer & Database modes Only the AGENTS.MD in the current library is loaded IBM TechXchange | © 2026 IBM Corporation 12
13. Force with May the Bob bebe with usyou Define the rules in .md — Bob reads them on its own Pull the source to local — via Premium Package for i Just say “create new RPG"— back to IBM i and compiles Works for Python, too — already in action IBM TechXchange | © 2026 IBM Corporation 13

17. 開発標準をもとにBobが作ったAGENTS.mdとSKILL.md AGENTS.md SKILL.md ## 開発ガイドライン ## RPGコーディング規約 ### RPGプログラム開発時の注意点 1. **ファイル定義** ### サンプルプログラム構成 - 必ずエラー処理を有効化（E指定） Back_Sampleフォルダ内に郵便番号マスタメンテのサンプルプログラムを配置 - 更新処理ではCOMMIT制御を指定 Guideline Common #### 物理ファイル (PF) 2. **パラメータ定義** （開発ガイドライン） - **AAMPSTP.dds**: マスタ物理ファイル（サンプル：郵便番号マスタ） - 入出力パラメータは明確に分離 Rules - 標準パラメータセットを必ず含める #### 論理ファイル （共通ルール） (LF) - **AAMPSTL01.dds**: マスタ論理ファイル01（サンプル：郵便番号マスタ） 3. **初期化処理** - 出力パラメータは必ず初期化（#S870サブルーチン） #### RPGプログラム - 標識は`MOVEA *ALL'0' *IN(01)`でクリア - **AASMI010.rpgle**: 明細取得プログラム（サンプル） - **AASMI011.rpgle**: 単票取得プログラム（サンプル） 4. **ファイル操作** - **AASMI012.rpgle**: 更新電文プログラム（サンプル） - キー指定読込は必ず標識でチェック - 論理削除はMADELTフィールドを使用 ### プログラム構造規約 5. **トランザクション** #### 1. ヘッダー部 - 更新処理は必ずCOMMIT/ROLBKで制御 ```rpg - エラー時は必ずロールバック ********************************************************************** * 6. **終了処理** *プログラム : [プログラムID] - 継続処理がない場合は`SETON LR`で終了 * :[プログラム名称] - 正常終了時は適切なメッセージをセット * *作成者 : [作成者名] [作成日] ### フロントエンド開発時の注意点 *変更者 : *変更内容 : 1. **JDBC接続** * - IBM i Toolbox for Java使用 ********************************************************************** - 接続プールの適切な管理 H DATEDIT(*YMD/) ``` 2. **RPGプログラム呼び出し** - パラメータの型と桁数を厳密に一致させる - 文字列は必ずパディング処理 3. **エラーハンドリング** - リターンコード、結果コードを必ずチェック - メッセージは適切にユーザーに表示 Trigger phrases & Gather Requirements （呼び出し条件とヒアリング） Apply Coding Standards （規約の適用） Copyright 2026 IGUAZU Corporation 17
