Okay Robert. 
Then what about next solution:

1) Valentina define several global assoc array, to simulate enums of other
languages. Names will be again similar:

    EVDebugLevel   
    EVDbMode
    EVFlags
    ...

And Now you can write

    SqlSelect( 
        query, EVCursorLocation["kServerSide"], EVAccess["kReadWrite"] )


Only problem, I think this way will have slower access to constant values.
