I understood "spawn" from this discussion to provide access to a CLI, but what is valid from that point on certainly varies between operating systems, and as I understand it, even between Unix variants. In general it would seem that portability of access to "system" capabilities is not helpful between domains where those capabilities are not identical. Larry Kilgallen
