Hi Bruno,

You can use 'select with a little trick

>> firstvalue: 1
== 1
>> secondvalue: 2
== 2
>> searchblock: reduce [firstvalue secondvalue firstvalue]
== [1 2 1]
>> select searchblock firstvalue
== 2
>> select searchblock secondvalue
== 1
>> select searchblock firstvalue
== 2
>> select searchblock secondvalue
== 1

Regards
Patrick
