21: .SH DESCRIPTION
22: .I Ped
23: is an interactive drawing program for
24: 5620 terminals.
25: A
26: .I file
27: argument is equivalent to
28: an
29: .L e
30: command as described below.
31: Most features of
32: .I ped
33: are menu-controlled and self-explanatory; further details
34: are in the reference.
35: .PP
36: Button 1 selects actions
37: from a permanent menu and to draw or pick up an object.
38: Button 3 terminates drawing actions or changes
39: the permanent menu.
40: Button 2 causes the permanent menu to revert to
41: .LR basic .
42: .PP
43: The operation of
44: .I ped
45: is split between host and terminal.
46: When a file is first read, it is kept on
47: the host;
48: .L bring in
49: gets it to the 5620.
50: .PP
51: Option
52: .B -f
53: causes
54: .I ped
55: to display all text in one size to save time and space.
56: .PP
57: Some of the actions on permanent menus (switched by button 3)
58: are described below.
59: The last action is usually remembered and may be
60: executed repeatedly
61: until another is selected.
62: Thus, for example, one can fill many polygons with
63: one button click per polygon.
64: Actions marked
65: .L (t)
66: in the menu toggle on and off.
