RE: Journal API Troubleshooting -- RPG400-L

As other have pointed out, you need to change your '4B 0' entries to '10i
0'.

You also need to change some of your initialization values.  You are
currently initializing RecCount to 100 meaning that you are passing 100
keys to the API.  You are actually only sending 1 and so RecCount should be
set to 1.

You also have VarLenRecLen being set to 285.  This should be 46 (the summed
sizes of VarLenRecLen, Key, KeyLen, FileElemCount, Filename, Library, and
Member).

Making these changes should get you quite a bit along in retrieving the
journal entries.

Thanks Scott!!  That worked.  Using APIs is pretty cool!



The descriptions provided by IBM are sure difficult to decipher.  Now I am
trying to send a selection parameter, selecting one file (parm 5), and the
API document seems to outline it as follows:



Journal Entries to Receive  Char(*)

Format:



Bin(4) Number of Variable Length Records

Char(*) Variable Length Records

Format:



Bin(4) Length of Variable Length Record

Bin(4) Key

Bin(4) Length of Data

Char(*) Data

Format:



Bin(4) Number in array

10A Filename

10A Library

10A Member



Whew.  It took two cups of coffee to extract all that from the document,
but
I translated it into the following data structure:



     D JournalSelect   DS                  Qualified

     D  RecCount                      4B 0 Inz(100)

     D  VarLenRecLen                  4B 0 Inz(285)

     D  Key                           4B 0 Inz(16)

     D  KeyLen                        4B 0 Inz(34)

     D  FileElemCount                 4B 0 Inz(1)

     D  Filename                     10A   Inz('TRANS')

     D  Library                      10A   Inz('E06FILES')

     D  Member                       10A   Inz('TRANS')



When I add the JournalSelect to the Call(P) statement, I get the following
error:



CPF3C82 - Key 123865 not valid for API QjoRetrieveJournalEntries



Now, the value 16 is supposed to be sent as the key.  So I tried viewing
the
data structure in hex, and attempted to decode the value 123865 into
binary,
then hex, to determine where it is grabbing the key value from, to adjust
my
data structure, but I am not sure how the binary coding works for
negative-capable fields.



So I am stuck again, any help would be greatly appreciated.
