36 Screen Updating and Cursor Movement Optimization:

55 This document describes a package of C library functions
56 which allow the user to:
59 update a screen with reasonable optimization,
62 get input from the terminal
63 in a screen-oriented fashion,
67 independent from the above, move the cursor optimally
68 from one point to another.
70 These routines all use the
71 \*(tc \*(db to describe the capabilities of the terminal.
75 This package would not exist
76 without the work of Bill Joy,
78 in writing his editor,
79 created the capability to generally describe terminals,
80 wrote the routines which read this \*(db,
81 and, most importantly,
82 those which implement optimal cursor movement,
83 which routines I have simply lifted nearly intact.
84 Doug Merritt and Kurt Shoens also were extremely important,
85 as were both willing to waste time listening to me rant and rave.
86 The help and/or support of
93 also greatly appreciated.
94 .i "Ken Arnold 16 April 1986"
96 The help and/or support of Kirk McKusick and Keith Bostic (public vi!)
97 was invaluable in bringing the package ``into the 90's'', which now
98 includes completely new data structures and screen refresh optimization
