I've created what I call a "tally calculator," which gives an AS/400 user the

ability to tally a batch of numbers. Using the REXX language built into OS/400,

I was able to create the program (called a "procedure," in REXX terms) with

very little effort.

1 contains the source code. When you create the source member, specify

Figure 1 contains the source code. When you create the source member, specify

REXX as the source member type. No compiling is necessary since REXX interprets

the language statements as it executes.

To run the procedure, use the Start REXX Procedure (STRREXPRC) command and

specify the source file and library that contains the REXX source member. This

REXX procedure illustrates how useful the REXX language can be.

  • 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:
