Clipper Applications and Triggers

$

Hello Everyone,

 

We are running ADS 10.1. We have an in-house developed ERP that was built in Clipper 15+ years ago. The clipper applications that we use do not utilize SQL statements through an RDD, just navigational database changes.

 

This help page (What is a Trigger?) seems to state that triggers can be used with navigational database changes, but they don't seem to be working for us. I created a simple trigger in a data dictionary in the ARC utility, and tested both SQL statements and a function in our Clipper programs that update the same record. When I used a SQL command, the trigger successfully executes, when our Clipper program changes the record, the trigger does not execute.

 

What do we need to do to make triggers execute for non-SQL database procedures? Is what we're attempting to do even possible?

 

Thanks for your time!
