You need an accumulator which is a reversed counter: Instead of [f ]x[+ 1] you do: [+ ]x[f ] And then instead of a bang as in a counter you send numbers in: Send a 1 for a new visitor and a -1 for a leaving visitor: [r visitor-comes] | [r visitor-leaves] | | [1( [-1( | / | / |/ [+ ]x[f ] | [s visitor-count] Ciao -- Frank _______________________________________________ [email protected] mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
