Qn 25: How can more values be returned from one particular function?
Ans Convert the function to procedure?

While ugly, you can return additional outputs:

function foo returns logical (
   output o_cbar as char
):

   o_cbar = "bar":u
   return true.

end function.

But you may be better off returning an object:

function foo returns foobar (
):

   foobar = new foobar().
   foobar:cbar = "bar".

   return foobar.

end function.
