RE: Programming a trigger audit in ILE

[rob@xxxxxxxxx]

Sad to say, but I got in the habit of not modifying the library list in my 
trigger programs.  I hardcode everything.

Keeping in mind that a trigger program on a file is called when activity 
happens on that file.  And, that activity may be initiated by something 
other than your favorite 5250 application.  For example:
- a UPDDTA  in a job with QUSRLIBL library list
- An excel application
- a web application
- Domino
- and the list goes on.

Is anyone using a CLP as the trigger program?  I am creating an audit file 
from an *Update trigger, however, was wondering how to keep the library 
list straight so the program that called the trigger program completes 
normally.   The Sorcerer book says a CLP can be used, however, it appears 
that RPG is the suggested route.

Barbara's absolutely right.  I pulled the example from the wrong program.
My trigger maps look like this:

D TrgBuf        E DS                  EXTNAME(Trigger) 
 
 * We can't tell how many fields are in the file; 
 * to avoid hard-coding the number, set up an arbitrarily large 
 * array to hold the null map.  Remember that you can only 
 * trust the array up to the null map length!!! 
D OldNulImg       ds         32766    Based(POldNul) 
D  OldNulMap                     1a   dim(%size(OldNulImg)) 
D NewNulImg       ds         32766    Based(PNewNul) 
D  NewNulMap                     1a   dim(%size(NewNulImg)) 

 * Map the file I/O buffers from the external definitions
D OldRcdImg     E DS                  EXTNAME(DATESAMPLE)
D                                     based(pOldRcd) 
D                                     prefix(O_) 
D NewRcdImg     E DS                  EXTNAME(DATESAMPLE)
D                                     based(pNewRcd) 
D                                     prefix(N_) 

C     *Entry        Plist 
C                   Parm                    TrgBuf 
C                   Parm                    TrgBufLen
C                   Parm                    TrgRtnCde

C                   EVAL      pOldRcd = %ADDR(TrgBuf)+ Z1OROFF
C                   EVAL      pOldNul = %ADDR(TrgBuf)+ Z1ORNBO
C                   EVAL      pNewRcd = %ADDR(TrgBuf)+ Z1NROFF
C                   EVAL      pNewNul = %ADDR(TrgBuf)+ Z1NRNBO

Sorry for the snafu, and thanks, Barbara!
