TechTalk: Recycling OPNQRYF

From: Dennis Ball To: All

I was hoping someone else encountered this problem. Although we have used OPNQRYF quite a bit, we have a recurring problem. After running the OPNQRYF command, we run a program and it runs perfectly. The second program can't get the OPNQRYF-it seems that the file closes. We have tried several changes to get the file to stay open, i.e., *PERM, but that hasn't worked. We don't want to run the OPNQRYF twice and we don't want a logical file. Anybody have the answer?

From: Ted Holt To: Dennis Ball

There are two ways to reuse an OPNQRYF command. The easy way is to use a POSDBF command between the two calls.

OPNQRYF ... CALL PGMA POSDBF OPNID(XYZ) POSITION(*START) CALL PGMB

The other way is to have the second program reposition the file pointer, using a command such as RPG's SETLL or COBOL's START verb.

  • 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:
