I've used a trick with 'set' for something similar, so perhaps
this will work for you:
set -- allow 'deny log' 'pipe 10'
while [ $# -gt 0 ]; do
act=$1
# do stuff here
shift
done
You can also use 'eval', but that makes escaping nasty. It may be
possible to change the IFS to something other than space, but I've
never messed around with that particular black magic.
