It may wind up being messier to keep track of than the change in your callpipe, but you can connect a new output stream: 'addstream output xtra' 'addpipe *.out.xtra: | take 0' If there was already an alternate, the new one will just harmlessly go unused. I've never quite gotten why that ADDPIPE is needed. Without it, you get message FPL139E: No connection available to redefine for *..1: But you don't get that message for a stream that's initially defined but unconnected. > And, what do I have to do that MAXSTREAM IN and MAXSTREAM OUT give > different results? ADDSTREAM INPUT or OUTPUT. ¬R
