Updateable Cursor in VFP 3

My company still has a couple of production applications in Visual FoxPro version 3 that I have to make maintenance changes to from time to time.

In VFP 7, when you create a cursor, you can make it updatable by using the READWRITE keyword. Unfortunatly, this cannot be done in VFP 3. Below is a work-around that will make a cursor read-write.
