Thank you for your response.
I have an error routine that is specific for the developer.

When an error occurs, the programmer gets the choice of either having the error routine set a breakpoint (thanks for your help on that as well) on the offending line of code, or it activates the command window and via the KEYBOARD command releases the object and issues an EDITSOURCE() to direct them to the problem. I've got all that working, but knowing the level of inheritance at which the activity occurs becomes relevant, so that the breakpoint or EDITSOURCE() can be correctly applied.

Thanks for your attention.
