Comments and questions about EMODE should be addressed to Will Galway

@Comment{The following text should really be implemented as an include
file? Shared with EMODE.MSS?}
EMODE is available as a "loadable" file. It can be invoked as follows:
@begin[example]
@@PSL:RLISP
[1] load emode;
[2] emode();
@end[example]
Of course, you may choose to invoke RLISP (or "just plain Lisp")
differently, and to perform other operations before loading and running
EMODE.
EMODE is built to run on a site dependent "default terminal" as the default
(a Teleray terminal at the University of Utah). To use some other terminal
you must LOAD in a set of different driver functions after loading EMODE.
For example, to run EMODE on the Hewlett Packard 2648A terminal, you could
type:
@begin[example]
@@PSL:RLISP
[1] load emode;
[2] load hp2648a;
[3] emode();
@end[example]
The following drivers are currently available:
@begin[description,spread 0]
AAA@\For the Ann Arbor Ambassador.
DM1520@\For the Datamedia 1520.
HP2648A@\For the Hewlett Packard 2648A (and similar HP terminals).
@Comment{Should we be this specific?}
TELERAY@\For the Teleray 1061.
VT52@\For the DEC VT52.
VT100@\For the DEC VT100.
@end[description]
See the file PE:EMODE.LPT for information on creating new terminal drivers.
When EMODE starts up, it will typically be in "two window mode". To enter
"one window mode", you can type "C-X 1" (as in EMACS). Commands can be
typed into a buffer shown in the top window. The result of evaluating a
command is printed into the OUT_WINDOW buffer (shown in the bottom window).
To evaluate the expression starting on the current line, type M-E. M-E
will (normally) automatically enter two window mode if anything is
"printed" to the OUT_WINDOW buffer. If you don't want to see things being
printed to the output window, you can set the variable !*OUTWINDOW to NIL.
(Or use the RLISP command "OFF OUTWINDOW;".) This prevents EMODE from
automatically going into two window mode when something is printed to
OUT_WINDOW. You must still use the "C-X 1" command to enter one window
mode initially.
