.SH DESCRIPTION
.I Ped
is an interactive drawing program for
5620 terminals.
A
.I file
argument is equivalent to
an 
.L e
command as described below.
Most features of
.I ped
are menu-controlled and self-explanatory; further details
are in the reference.
.PP
Button 1 selects actions
from a permanent menu and to draw or pick up an object.
Button 3 terminates drawing actions or changes
the permanent menu.
Button 2 causes the permanent menu to revert to
.LR basic .
.PP
The operation of
.I ped
is split between host and terminal.
When a file is first read, it is kept on
the host;
.L bring in
gets it to the 5620.
.PP
Option
.B -f
causes
.I ped
to display all text in one size to save time and space.
.PP
Some of the actions on permanent menus (switched by button 3)
are described below.
The last action is usually remembered and may be
executed repeatedly
until another is selected.
Thus, for example, one can fill many polygons with
one button click per polygon.
Actions marked
.L (t)
in the menu toggle on and off.
