Yes, but according to (I think) Matt Dillon it doesn't work right. I don't know if that means it's hard to get right or if there's a bug in AmigaDOS triggered by a task having multiple outstanding requests, but I trust the source enough to not want to try it myself. Browser does its own packet I/O to implement a four-argument Rename(), but doesn't do multiple requests at a time. -- Peter "Have you hugged your wolf today" da Silva <peter@sugar.hackercorp.com> `-_-' 'U` "I haven't lost my mind, it's backed up on tape somewhere"
