Use the ActiveControl property of the container and then parse out the alias and field name from the ControlSource property of the ActiveControl:

loControl = oForm.ActiveControl
lcAlias = SUBS(loControl.ControlSource, 1, (AT(".", loControl.ControlSource) - 1))
lcField = SUBS(loControl.ControlSource, (AT(".", loControl.ControlSource) + 1))

This is all you need for OLDVAL() and CURVAL()

WARNING Getting the ActiveControl from a grid requires a little extra work.

This last one causes the question. I haven't found any way to reference the edit buffer field except for 'tablename.fieldname'. Is there a way to do so using variables?
