Hi Rodney
One nice way to do this is:
>> one: false
== false
>> two: false
== false
>> three: true
== true
>>
>> any [all [one print "1"] all [two print "2"] all [three print "3"]]

Notice that ANY and ALL can return the values of any expression as well as
just true and false. BTW, the construct above has the same functionality as
a COND in Scheme or Lisp.
