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!
