Re: After Read trigger fires multiple times

Here's an interesting tidbit...

I tested using code shown below:

C                   Eval      Counter = *Zero  
C     *Loval        Setll     RPMAST 
C                   Dou       Counter = 10 
C                   Eval      Counter = Counter +1 
C                   Read      RPMAST 
C                   Enddo 

The *loval setll fired the *After *Read trigger !!!

No one on our staff (5 other programmers) thought this would happen. 

I always thought (and confirmed by re-reading the SETLL opcode at the 
infocenter) that setll doesn't actually read the record. My job shows a 
zero for the I/O count on the file, but in debug, the buffer clearly shows 
the contents of the first record in the file.

As a result of this test using the above code, the trigger fired 11 
times....

Also - I'm at V5R2 and my trigger programs are using the trigger template 
programs provided by Jon Paris & Susan Ganter from an article found at the 
following link: 
http://www.eservercomputing.com/iseries/articles/index.asp?id=169

I been using trigger programs (from these templates) for other stuff with 
no problems. This is my first use of the *READ activity.

Query worked as expected. My file has 1001records, and I ran an 
interactive query and positioned to the bottom and the triggered fired 
1001 times.
