Nope.  May as well add another parameter to indicate status back to the
caller.
d stripemail pi     like(emailaddress)
d   sourcestring     512a const
d   returncode          10i 0

An alternative is a bit more C-like
d stripemail pi   10i 0
d   sourcestring     512a const
d   returnstring          like(emailaddress)

Null support isn't yet what we hoped for.
