Triggers

Hello, all.

I want to monitor a statusfield, STATUS i file A.  If the STATUS is canged 
to a certain value, I want a pgm, PGMA to start.  PGMA will use data from 
the changed record.

Any examples on how to do this?  I've been looking at ADDPFTRG, and I can 
see that a record update can trig a program.  But how can I get data from 
the updated record into the trigged program? 

Is this an effective way of doing this?  This program will be started 
every time a record in the file is updated, and it is just a few values 
that will get my pgm running.  Alternatively I can run a batch-program at 
the end of day and find out the same?


Mvh.
