I've never used cursors in this way so my help is more t= heory but:

The called-function already created the cursors.  I= n the parent function you should simply be able to pass them through unalte= red:

SELECT * INTO v_outvar1, ...;

You can possible simply the above and to= ss the temporary variables but that should not impact the semantics.
