• Guru Classic: A Bevy of BIFs — %CHAR, %EDITC and %EDITW

  February 13, 2019 Jon Paris

  Author’s Note: The reason I chose this particular tip to revisit was that a similar question came up on one of the RPG web forums the other day. The questioner was looking for an easy way to edit a numeric field to include the use of colons as separators. Because the answer involves the use of %EditW I have added a simple example of its use at the end of this tip.

  “I need to convert a numeric value into a character string. How do I . . . ?” This question is often asked by RPGers as they face …

• Guru Classic: A Bevy of BIFs – %SCAN and %CHECK

  January 16, 2019 Jon Paris

  Many RPG programmers seem to get confused about the usage and operation of a number of built-in functions (BIFs). In particular the BIFs %XLATE, %REPLACE, %SCAN, and %CHECK seem to cause a lot of confusion. In this tip, I focus on %CHECK and %SCAN. I decided to re-visit this particular tip because of the recent introduction of %SCAN’s companion BIF %SCANR and a related enhancement to %SCAN itself. More on this later.

  The %SCAN BIF has been with us since V3R7, when it was introduced along with %EDITC and %EDITW, to improve string handling. %CHECK, on the other hand, is …

• Latest IBM i TRs To Ship Next Month

  August 15, 2018 Alex Woodie

  IBM unveiled a pair of out-of-bound technology refreshes (TRs) for the IBM i operating system last week. In addition to supporting the new Power Systems E980 server, IBM i 7.3 TR5 and 7.2 TR9 bring a set of enhancements to the platform’s database, development tools, and the administrative interface.

  The IBM i installed base has grown accustomed to seeing operating system updates in the spring and the fall. This twice-a-year pattern has been with us, more or less, since IBM shifted to the TR approach several years ago. But IBM broke with that tradition last week when it announced that …

• Guru: A Bevy of BIFs – %Dec to the Rescue

  August 1, 2018 Susan Gantner

  Author’s Note: This tip was first published back in 2009. I’ve updated the code examples here to use free format declarations. In addition I’ve added the potential use of %ScanRpl, which didn’t exist at the original publication date.

  More and more in RPG applications these days, it seems we need to process data that comes from “the dark side.” Translation: from a non-i system. This data could be coming from a browser screen via an RPG CGI program, from a CSV (comma-separated values) flat file, from an XML or JSON document, or myriad other ways. One thing these dark sources …

• PTC Refines Handling Of IBM i Database Logic

  July 18, 2018 Alex Woodie

  More organizations are moving business logic from RPG and COBOL programs into the DB2 for i database, which most community members agree is a good thing. The IBM i server’s core strength is its integrated a database, after all. However, when business logic moves into the database, it requires customers to rethink how they’re managing the code, which is a mantle that PTC has taken up with its Implementer software change management (SCM) tool.

  When it comes to application modernization, fancy HTML5 screens and mobile apps usually grab the spotlight. We’re often moved by the things we can see, and …
