Insert records into related file based on conditio

[BikeBoy]

Hi, long time no write,

I have a question, what's the best way to insert records into related file based on specific condition, something akin to a trigger in RDBMS.

I want to attach this script to creating a new record that meets specific condition in FileA, and then insert a record with sp[ecific values into FileB.

I want to do this without plug-ins, I'm aware that oAzium Events plug-in will do this.

Thanks
