Is it possible to have FileMaker execute a script whenever a particular text field becomes "not empty"?

I have a layout with a text field that is normally blank. If the user drags a text string from another field into the empty field, I would like to immediately process the request without the user having to click on a button. Is this possible without a third-party plugin?

Thanks in advance.

Hi

can you precise better "immediately process the request"...

because maybe that you don't need to fire a script.

In that case the particular text field can be modified to an AutoEnter/Replace text field.

Thanks for your response.

Yes, I had been thinking that I could use a global calculated field to perform part of the process I need, which is to append the "dropped text" to another field to get a useful result. The main problem is that I don't know of a way to clear the field back to it's original (empty) state. If I could execute a script, I would of course use SetField(Table::Field;""). From a larger perspective, however, I can think of many interesting possiblities for other features if I can find a way to initiate a script upon the drop action.
