V4MD1 SetBlank()

[Andrew Sinning]

In the docs for AddRecord, is states "If you specify the list of field 
values, you can skip call of SetBlank() because it will be made
by Valentina." 

Is this a mis-print?  Should it say that UpdateRecord() can be skipped?

I think I misunderstand the use of SetBlank().  I've been thinking of it 
as a way of dropping the connection to the record-set, or the cursor.  
Please explain SetBlank(). 

It looks to me now that in order to drop the cursor, the variable has to 
be voided, or set to 0.  Is that correct?

The reason this has come up, is that I am noticing that if I call 
another handler withing voiding out (theCursor = void) my current 
currsor, then the sub-handler is not able to create a new cursor.  Is it 
not allowed to have multiple cursors open at once with V4MD1?
