That works quite well... now I'll try to use the idea as verb in a cut or a scan. I'd like to have state. I've looked at ;: for quite a few weeks, but it doesn't seem to handle more than an array of rank 1 input as input.
Also, I'd like to do a few FSMs in parallel + handle interaction between them, and do some calculations. Am I asking too much for one line? --Steven ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
