    ... Is it possible to tell LISP to  send a string to TWENEX
    and have it process it?  I've tried using VALRET, but it doesn't
    seem to work as it does on ITS.

Empirically, I note that VALRET works in a subtlely different way than 
on Twenex than on ITS. If there is input pending after a program is entered
and that program doesn't use that input, the input is discarded. eg,
(VALRET "F
")
will work to invoke finger, and
(VALRET "RESET .
F
")
will work to kill the current fork (RESET is a monitor command, not a 
program), but
(VALRET "F
CONT
")
will end up with the CONT discarded, where the analagous 
(VALRET ":F
P")
would work just fine on ITS. Other than this misfature (and the amazingly
losing habit Twenex has of typing "@" even tho' it's not going to echo the
valretted text), VALRET seems to work reasonably for me, also.
