RE: QWVOLAGP API and CWBRXD window

["David Morris" <dmorris@xxxxxxxxxxxxx>]

Richard,

I have always used them together.  You open a list and 
then use the list processing APIs to retrieve your records.  
If you specify a number of records that exceeds the number 
you expect to have returned, you could probably get away 
without using the retrieve list entry API, but that is not 
going to gain you very much.  Once you are done with a list 
you will want to call the close list API to end the server.

The QGY... retrieve list entry API just retrieves elements 
from a list that is being built.  The list is built in a 
separate process.  You use the status codes returned in the 
list header to determine how many list entries are available 
and whether the list is complete (or in error).  Once you are 
done, you close the list.

Like I said, I don't have any code specific to the activation 
group lists, but the general processing should be the same 
for any type of list. I don't have any code here at work that 
uses a list so I can't post that but here are some structures 
that define the common list fields and the close/retrieve 
record API calls.  Take a look at this and let me know if you 
have any more questions.  I will try to remember to forward 
an example of how these are used.

The information that I have, says that the QWVOLAGP API generates a list of
all activation groups and their attributes for a specific job. It says the
APIs that start with QGY just retrieve more records. I am having a hard time
understanding, how they all work together. 
Does the list processing APIs (start with QGY) also return information about
the activation groups for a specific job?

Thanks in advance.
Richard
