Passing more than one variable out of a function. [message #65849]

The IDL intrinsic function WHERE can pass more than one variable out
to the calling program.

For example:

> array=[0,2,4,6,8,10]
> arr_subscripts = WHERE(array GT 5, count)

> print, arr_subscripts
3,4,5

> print, count
3

The question is how can I write a user defined function which can pass
more than one variable out to the calling program. Just like the WHERE
function?

I know that I could just use a procedure to do this. But I am just
curious.
