If EmailAddress is a pointer, you can return *NULL (so I guess it's not
a pointer :).  If it's a varying string, you could return ''.  If you
mean something like an ALWNULL field, you can't.

You could define a named constant with your prototype with a value that
is nonsense for your procedure.

D STRIPEMAIL_NULL    c            'x'

caller:
    ret = STRIPEMAIL (string)
    if ret = STRIPEMAIL_NULL
       ...

Stripe Mail? (Ya, I know, Strip Email).
