Locians, Guess what I think is our best candidate for wrapping various command-line "instruments" (analysis loci)? You might have heard of "Expect", which is written for Tcl by Don Libes. Tim O'Mally wrote a "poor man's Expect" as a Python module. exploop.py requires eventloop.py. Both are attached, if anyone wants to play around with them. Enjoy, Jeff -- J.W.
