Hello Everybody,

Have a number of SIMPLE questions regarding a trigger Implementation.

These are the questions, and hopefully your experiences can give me
 guidelines for the writing of the trigger programs.

1.-    I read in the v4r2 DB2/400 Programming Book that Recursive
        Triggers are supported and the maximum number of recursions is 200

        Question: Is this Recursion Supported in V3R2 and if it is
                            what is the maximum number of recursions ?

2.-   Because of the nature of the recursion ... Do I need to create
        an ILE program ?

        Is there a  Simple *AFTER Update, Recursive Trigger
        Example anywhere ?

3.-   I Only Need 1 Level Of Recursion........
        I have contemplated to have a *DTAQ  BATCH program
         running in the background to simulate the Recursive
         Update. Is there any problems with this approach ?

 4.-   Can I Just simply Update the NEW_RCD area
          in the *BEFORE Update Trigger and let the
          *AFTER Update Trigger Occur, eliminating the need for recursion ?

  Thanks for your response.

   Regards                                Jorge Moreno / Military Car Sales

 PS. David ... How about a  NEW archive of TRIGGERS and data base Issues ?
