• Guru: Copy From Stream File FMTOPT(*NOCHK)

  April 13, 2020 Bob Cozzi

  Using SQL frequently, as I do, I tend to look for solutions to problems that can be resolved using the database language (i.e., SQL). Sometimes I have to invent a missing piece of the puzzle. Often that entails writing a User-Defined Function (UDF) for use in SQL, but sometimes a CL command is the better choice.

  Recently I had a situation where what the client calls an “EDI File” was being downloaded using sftp on the IBM server running i. This file is created at a vendor that runs IBM mainframes (an actual mainframe by the way) and the file …

• Guru Classic: Overlaid Packed Data In Data Structures

  March 4, 2020 Jon Paris

  When I re-read this tip while looking for a “Classic” candidate, I was reminded that the underlying issue it addresses, namely how data is actually stored in an RPG program, is one that many RPG programmers don’t really have a firm grip on. That alone made it a good candidate. But perhaps even more important is demonstrating this topic to the many new programmers coming onto the platform. Unlike those of us who started off with assembly languages, C, RPG, or COBOL, modern programmers trained in C#, Python, or PHP have never had any need to understand the mechanics of …

• Microsoft Wants to Migrate Your IBM i Code to Azure

  November 13, 2019 Alex Woodie

  Microsoft is executing a plan with its partner Skytap to bring IBM i into its Azure cloud, as we’ve previously told you about. But another group within the technology giant has plans of its own to migrate IBM i applications to languages that can run natively on X86 servers and integrate more easily with Azure services.

  We caught wind of this group’s code migration plan a month ago when one of the technical specialists in the Microsoft Azure Global Customer Advisory Team (CAT) wrote a blog entry about the work they do. IT Jungle followed up with the IBM i …

• IBM i TRs Bring Database Enhancements, Too

  October 30, 2019 Alex Woodie

  The heart of the IBM i server is its database, so it’s natural that we would see some enhancements to Db2 for i with delivery of IBM i 7.4 Technology Refresh 1 and 7.3 TR 7 next month. The new features may not be earth-shaking, but they deliver some useful functionality nonetheless.

  Let’s start with some foundational changes to the database itself, including the way that database engineers architect the tables that store information in the database. With 7.4 TR1, IBM i shops can now add a new child table to the database without having an exclusive lock on the …

• ARCAD Unveils GUI Modernization Tool

  September 25, 2019 Alex Woodie

  ARCAD Software is getting deeper into the application modernization business with the launch of iNow, a new tool designed to help IBM i users create compelling graphical user interfaces (GUI) that run across Windows, Web, and mobile form factors. The new offering, which is based on Microsoft .NET and utilizes Remote Desktop Protocol (RDP) technology, is being sold as part of a new suite called ARCAD for IBM i Modernization.

  IBM i shops have been adapting their applications to Windows interfaces for the better part of 30 years, to the Web for about 20 years, and to mobile interfaces for …

• Guru: Enumerated Data Types In RPG

  September 16, 2019 Ted Holt

  IT has changed a lot since I entered the field several decades ago, but some things have not changed. I would read in those early days that COBOL was dead, and I read the same thing now. Yet COBOL is 60 years old and still going strong. Back then I heard RPG criticized as “Real Poor Garbage”. These days I hear it scorned as “legacy”, which I assume is supposed to mean the same thing. Yet today’s RPG is better than any of its predecessors for business programming.

  RPG supposedly does not have the features of modern languages. Maybe not, …

• Remain Breaks New Ground With ALM Suite

  July 15, 2019 Alex Woodie

  Coding season just ended for Remain Software, the Dutch application lifecycle management (ALM) vendor with a growing US presence. That means customers are sorting through a torrent of new functionality in its flagship TD/OMS product, including improved hooks to DevOps tools like Git and Jenkins, a new cross-platform cross-reference module, and a nifty API generator too.

  New stuff started emerging from Remain Software around the POWERUp conference in May, when IT Jungle sat down with company representatives to talk about development trends, current and upcoming releases of Remain’s software, and what customers are looking to get next.

  Arguably the biggest …

• Guru: Preamble Comments

  April 15, 2019 Chris Ringer

  Do you remember what you ate for lunch two days ago? If you’re like me, you had to think about it for a minute before answering. Now imagine trying to recall the detailed requirements of a few programs you wrote a year ago so you can modify them for a new project. Or better yet, what if someone else like a retired employee or a traveling contractor coded these programs? At this point you may become very dependent on any comments they left in the code.

  It’s been said that any time spent commenting on your code now might save …

• What New Language Will IBM i Support Next?

  March 27, 2019 Alex Woodie

  The prospect of a new language coming to a platform is always reason for excitement. New languages bring new capabilities, or at least faster ways to tap into existing capabilities. The question for those living and working on the IBM i platform is what language will come next?

  RPG remains the go-to language used by the vast majority developers on the IBM i platforms. According to the 2019 survey by HelpSystems, 84 percent of coders on the box use RPG. COBOL, RPG’s partner in legacy crime, is also supported in the Rational Development for IBM i RDi, along with …

• Building Out The .NET Stack Around Mono for IBM i

  March 13, 2019 Alex Woodie

  The first release of a Mono .NET port to IBM i was issued last year. Since then, the IBM i open source community has been busy building many of the other middleware components that will make it easier for developers to build IBM i applications using Microsoft tooling.

  Mono was ported to AIX and IBM i (via the PASE AIX runtime) last year, which gave IBM i and AIX shops the capability to run the open source .NET runtime on Power Systems servers, thus opening the door to allowing Microsoft‘s highly regarded suite of development tools to be …
