Once upon a time, it was a rather tedious task to left-adjust decimal values and right-adjust character values with RPG. Nowadays, some of the more recent operation codes make the adjustments easy. 1 contains the source code for RPG subroutine ADJUST, which will left- or right-adjust the contents of a 30-byte variable. All you need to do is load the receiver variable field (RCVVAR) with the value you want to adjust and load the adjustment type field (ADJTYP) with an 'L' to left adjust or 'R' to right-adjust.

  • 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:
