TechTalk: Duplicate RPG Members Utility

A programmer from our shop wanted to modify an RPG III program. Because he wanted to use some new ILE functions, he converted it from Original Program Model (OPM) RPG to ILE RPG with the Convert RPG Source (CVTRPGSRC) command. Then he modified the new source in QRPGLESRC and compiled it. However, he made a big mistake: he didn't delete the old RPG source from QRPGSRC!

A few weeks later, another programmer needed to modify the same program. He looked in QRPGSRC and found the source. (He didn't know that the latest version was in QRPGLESRC.) He modified the RPG source and compiled it. As a result, we ended up with two different versions of the same program.

To avoid this situation, I wrote a utility called the Display Duplicate RPG Members (DSPDUPRPGM) command (see Figures 1 and 2). This utility checks a single library or all user libraries for QRPGLESRC files and looks for corresponding member names in QRPGSRC within the same library. If it finds any members with the same name in both source files, it displays them in a list.

  • SB Profound WP 5539More than ever, there is a demand for IT to deliver innovation. Your IBM i has been an essential part of your business operations for years. However, your organization may struggle to maintain the current system and implement new projects. The thousands of customers we've worked with and surveyed state that expectations regarding the digital footprint and vision of the company are not aligned with the current IT environment.

  • SB HelpSystems ROBOT Generic IBM announced the E1080 servers using the latest Power10 processor in September 2021. The most powerful processor from IBM to date, Power10 is designed to handle the demands of doing business in today’s high-tech atmosphere, including running cloud applications, supporting big data, and managing AI workloads. But what does Power10 mean for your data center? In this recorded webinar, IBMers Dan Sundt and Dylan Boday join IBM Power Champion Tom Huntington for a discussion on why Power10 technology is the right strategic investment if you run IBM i, AIX, or Linux. In this action-packed hour, Tom will share trends from the IBM i and AIX user communities while Dan and Dylan dive into the tech specs for key hardware, including:

  • SB HelpSystems ROBOT GenericForms of ransomware has been around for over 30 years, and with more and more organizations suffering attacks each year, it continues to endure. What has made ransomware such a durable threat and what is the best way to combat it? In order to prevent ransomware, organizations must first understand how it works.

  • SB HelpSystems ROBOT GenericIT security is a top priority for businesses around the world, but most IBM i pros don’t know where to begin—and most cybersecurity experts don’t know IBM i. In this session, Robin Tatam explores the business impact of lax IBM i security, the top vulnerabilities putting IBM i at risk, and the steps you can take to protect your organization. If you’re looking to avoid unexpected downtime or corrupted data, you don’t want to miss this session.

  • SB HelpSystems ROBOT GenericCan you trust all of your users all of the time? A typical end user receives 16 malicious emails each month, but only 17 percent of these phishing campaigns are reported to IT. Once an attack is underway, most organizations won’t discover the breach until six months later. A staggering amount of damage can occur in that time. Despite these risks, 93 percent of organizations are leaving their IBM i systems vulnerable to cybercrime. In this on-demand webinar, IBM i security experts Robin Tatam and Sandi Moore will reveal:
