SQL & PL/SQL :: Choose Explicit Cursor To Loop Through At Runtime?

Oracle Version: 11.2.0.2.0. I have two explicit cursors and I would like to choose at run time which one to run. Here is a simplified code snippet of what I am doing today:

DECLARE
CURSOR Cursor_A IS
SELECT * FROM EMP_A;
CURSOR Cursor_B IS
SELECT * FROM EMP_B;
RUNA CHAR(1) := 'Y';

[code]....

I want to avoid maintaining the same long list of transformations. I also want to avoid, if possible, an explicit FETCH INTO, because there are hundreds of fields in both tables. I'm looking for something like this (and I know this doesnt work):

DECLARE
CURSOR Cursor_A IS
SELECT * FROM EMP_A;
CURSOR Cursor_B IS
SELECT * FROM EMP_B;
RUNA CHAR(1) := 'Y';
CursorToRun IS REF CURSOR;

[code]....
