In general your class should have an array (or array property) which will contain the all opened cursors information, then loop through them and make the updates:

* DataManager class OnSave()  method.
FOR j = 1 TO ALEN(laTable,1)
	SELECT(laTable[j,1])
	this.Update()
NEXT

Update method will check all things like buffering, modified fields, error handler calls, etc.

You can find a sample of such code for example in Visual Extend framework
(http://www.devigus.com) in VFXOBJ.VCX - cDataTableMgr class.
