Field processing

I just wonder if processing field entries is possible at all ?
I would like to assign certain value to the variable after the data is entered into the field. I would expect something like “AfterFieldAccepted” event, but I do not see anything like that. I use some desktop 4GL tool and there are embed points for: “FieldSelected” , “FieldAccepted” which easily allow to process whatever is entered into the field. SC has no single field validation (ar perhaps I’m missing something) and that is something I keep asking for well over a year to implement.

Is there any way to set a global variable based on the field entry (without saving the form)?

What’s the difference to ajax events?
