2 Applies To: WAS 4.6 Summary Refactoring and By: Jayanta Narayan Choudhiri Company: Software Solutions and services Date: 29 Nov 205 Table of Contents SDN Community Contribution...1 (This is not an official SAP document.)...1 Disclaimer & Liability Notice...1 Applies To:...2 Summary...2 Table of Contents...2 Code...4 Author Bio...44 " Any fool can write code that a computer can understand. Good programmers write code that humans can understand. " --- Martin Fowler, Refactoring: Improving the Design of Existing Code ABAP pretty printer is good for code but not supportive for data declarations. 2

3 As a result ABAP code often tends to need more labour to maintain. I therefore wrote 3 Clipboard utilities. These are in a ZIP file and are available as a download. 1. YClipJNC based on but improved to include table~column half-line commenting. Take any ABAP code (should have survived syntax check) including that "." DOT terminator. Copy to Clipboard & F8 on YClipJNC will create the beautiful version in clipboard ready for pasting back. The big advantage is that you can send for beautification only portions of code - this is vital in maintaining someone else's badly written code. 2. YClip2JNC is for Internal Table declarations only, with existing comments Aligns everything nicely. 3. YClip3JNC is to create a Commented CALL FUNCTION Pattern. Try with "CS_BOM_EXPL_MAT_V2" The pattern is ready in clipboard for pasting appropriately. 3

4 These 3 utilities should give a big boost to good clean commented ABAP code. No excuses for not half-line commenting!
