TechTalk: Why a DDS Window Clears Screen

From: Michael Snider To: All

I am trying to use the new DDS window keywords. The program works, displays the window OK, but clears the screen before displaying the window. As there is no documentation provided for these keywords, I am asking for some help.

From: James Coolbaugh To: Michael Snider

Michael, if this window is in another program then you need to have another format in the display used by the called program that contains the ASSUME keyword. This tells the system to assume that this display file is already there, even though it isn't. You need this because the default for the AS/400 is to clear the screen when you open a new display file. The format that contains this keyword does not have to be used in your program; you just need it in the display file. Also consider using the KEEP keyword in the record that is displayed by the called program. This will prevent the screen from flickering when the called program is ended and the underlying panel is redisplayed.

  • 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:
