Guru: Speeding Up RPG By Reducing I/O Operations, Part 1
May 8, 2023 Gregory Simmons
Perhaps one of the easiest ways to speed up an RPG program is to reduce the number of I/O operations it needs to perform. In this article let’s explore one simple method for moving toward dataset processing.
Here I have a simple RPG program. Okay, admittedly, we don’t often get to write “simple” RPG programs, but for this example, I have stripped the RPG program down to just the read loop so I can demonstrate the conversion.
1 Dcl-f AcctMstr Usage(*Input) Keyed; 2 Dcl-pr entry ExtPgm('RPGRPT1'); 3 n Packed(3:0); 4 End-Pr; 5 Dcl-pi entry; 6 inBranch Packed(3:0); 7 End-pi; 8

April 24, 2023 Alex Woodie
IBM i professionals finally can access the Advanced Job Scheduler from Navigator for i as a result of the new Technology Refreshes (TRs) that IBM unveiled on April 11.

When IBM debuted the new Navigator for i in the fall of 2021 with release of IBM i 7.3 TR11 and 7.4 TR5, it figured it had the luxury of time …

IT Modernization Goes Beyond The Apps, Kyndryl Says
April 17, 2023 Alex Woodie
When the word “modernization” is said in the midrange and mainframe circles, it usually means application modernization, or transforming your older RPG and COBOL applications to look and feel like they just came off the Java or C# assembly line. But there’s another view of modernization that encompasses more than just the apps, and according to a new report from Kyndryl, there’s quite a bit of work to do.
While Kyndryl is certainly familiar with the application modernization needs of IBM i and System Z shops, the company (formerly IBM Global Technology Services) takes a broader view of the term, …

April 12, 2023 Alex Woodie

Like other software vendors in the space, Rocket Software has accumulated somewhat of a disparate collection of tools for the IBM i server. The Massachusetts vendor started its IBM …

Check out the Calendar below, which is becoming loaded with new events, so be sure to take a look. You will notice that the virtual option appears to be here to stay, and is …
