The one you have referred us to is definitely sufficient for our purposes. Thanks again.

Are you comfortable enough with the API usage?

I somehow overlooked/missed this API. Those that I did find dealt only with database files and not display files. This should do the job. The “business problem” , as it were, is to notify only certain workstations (not always the same) in a control center for a country-wide transportation system that a particular situation has arisen that demands attention. Identification of those currently active on the control application can be determined by a lock on an underlying display file that is not invoked other than by the control application itself.

Thanks for your help.
Zack

It’s not clear if that’s all that you need to know.

It might be useful if you described the business problem that you are trying to solve.
