MyField = Current value of field "Myfield". Includes the changes the user has just done.

oldval("MyField") = Values of MyField before the user made changes.

curval("MyField") = Value of MyField on disk. Visual FoxPro will read the field from disk again.

Except that if you are using views, then the data for curval() is read from the buffer. That means that if another user has made a change, it might not be reflected in curval().
