suppression of null record keys

Is there an environment variable or some config setting in jBASE that will prevent a programmer from attempting to write a record with a null record key?  I would prefer this work globally and not based on a particular file.  This system has a lot of very old code that has probably gone through several conversion prior to jBASE.   I am aware I could put a trigger on the file, but I'm finding this issue across multiple files and would like to resolve it quickly.   We're currently running jBASE 5.7 but will soon be upgrading to 5.8.  Thanks. 

Jim,

There is no such setting.

A trigger would be your best option here.

Thanks Mike

Jim,

The advantage of the trigger(s)  is that you have a chance to catch the culprit, whereas with a setting change, the problem could continue unmitigated.
