44: _G_p_a_c_k is a package designed to interface to the Chromatics
45: CG 3999 Color Graphics Terminal. The user must be familiar
46: with the Chromatics terminal and its capabilities. _G_p_a_c_k
47: maintains information on the state of each hardware window
48: and avoids the transmission of redundant commands. The fol-
49: lowing objects, defined as records, are known to _g_p_a_c_k:

122: constants and set window attributes at the start of any pro-
123: gram using _g_p_a_c_k. Procedures that are marked `internal' are
124: intended primarily for internal use by _g_p_a_c_k. Some pro-
125: cedures are generators that reverse their effects.
