TechTalk: Avoid garbage data being passed between modules in ILE.

CL

  • Smaller Small Medium Big Bigger
  • Default Helvetica Segoe Georgia Times

When passing parameters from a CL module to an RPG module, both of which are part of a single bound program, the length of alpha variables must be the same. For example, the receiving module needs 10 alpha characters if the sending module uses 10. If my sending module passes only eight characters, the program fills the last two characters with garbage.

This is different from the way we used to call Original Program Model (OPM) programs; we never had to worry about this. Now we must pad our sending parameter with the correct number of blanks so that the receiving module gets the correct data.

  • 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:
