Return *on or *off from CLLE module

I define a lot of my RPGLE modules with a return type of indicator. In the
module, I return *on for success or *off for failure. If I need more
details from the module, I include fields as part of a parm list. Then in
my code, I can write something like this



If DoesCustomerExist(customerNumber);

// execute code based on customer existing

Else

// execute code based on customer not existing

Endif



Is there a way to return the *on or *off from a CLLE module? RETURN does
not have a parm.
