How to return multiple values from a SAS/IML function if one of them is a vector?

[Salah]

Hello

I am trying to simulate data, since I need to call that data more than once in my code, I defined it as a function. The issue here is that I need to return that data (X) along with another numeric value that I called it (q). 

How can I do that?

Thank you

You can do either of the following:

1. Define your function to be a subroutine. If you use a subroutine, you can return multiple arguments.

2. Define your function to return a list. You can then access individual items in the list.

Using a subroutine is more efficient and doesn't have any learning curve. However, many programmers enjoy using lists to pack a bunch of related items into a single symbol.
