$#
Specify a delivery agent RHS delivery agent operator
The $# RHS operator
serves two functions. The first is to select a
delivery agent, and the second is to return the
status of a policy-checking rule set. We cover the
first in this section and the second in the
next.
When used as a prefix to the RHS or a rule set (except
when used in a policy-checking rule set), the
$# operator is
used to select a delivery agent. Consider, for
example, the following rule:
R$+ $#local $: $1
Here, the LHS looks for a workspace that contains a
username (without a host part). If such a workspace
is found, the RHS is then used to select a delivery
agent for that user. The selection of a delivery
agent is signaled by the $# prefix to the RHS. The symbolic name
of the delivery agent is set to local. The $: operator in the RHS
is described in $:
on page 676.
The $# in the RHS
must be used as a prefix or it loses its special
meaning. See Return a Selection: $#
on page 667 for a full description of this
operator.
