72<a name="index-TUI-configuration-variables"></a>
73
74<p>Several configuration variables control the appearance of TUI windows.
75</p>

78<dd><a name="index-set-tui-border_002dkind"></a>
79<p>Select the border appearance for the source, assembly and register windows.
80The possible values are the following:
81</p><dl compact="compact">
82<dt><code>space</code></dt>
83<dd><p>Use a space character to draw the border.
84</p>
85</dd>
86<dt><code>ascii</code></dt>
87<dd><p>Use <small>ASCII</small> characters &lsquo;<samp>+</samp>&rsquo;, &lsquo;<samp>-</samp>&rsquo; and &lsquo;<samp>|</samp>&rsquo; to draw the border.
88</p>
89</dd>
90<dt><code>acs</code></dt>
91<dd><p>Use the Alternate Character Set to draw the border.  The border is
92drawn using character line graphics if the terminal supports them.
93</p></dd>
94</dl>
95
96</dd>
97<dt><code>set tui border-mode <var>mode</var></code></dt>
98<dd><a name="index-set-tui-border_002dmode"></a>
99</dd>
100<dt><code>set tui active-border-mode <var>mode</var></code></dt>
101<dd><a name="index-set-tui-active_002dborder_002dmode"></a>
102<p>Select the display attributes for the borders of the inactive windows
103or the active window.  The <var>mode</var> can be one of the following:
104</p><dl compact="compact">
105<dt><code>normal</code></dt>
106<dd><p>Use normal attributes to display the border.
107</p>
108</dd>
109<dt><code>standout</code></dt>
110<dd><p>Use standout mode.
111</p>
112</dd>
113<dt><code>reverse</code></dt>
114<dd><p>Use reverse video mode.
115</p>
116</dd>
117<dt><code>half</code></dt>
118<dd><p>Use half bright mode.
119</p>
120</dd>
121<dt><code>half-standout</code></dt>
122<dd><p>Use half bright and standout mode.
123</p>
124</dd>
125<dt><code>bold</code></dt>
126<dd><p>Use extra bright or bold mode.
127</p>
128</dd>
129<dt><code>bold-standout</code></dt>
130<dd><p>Use extra bright or bold and standout mode.
131</p></dd>
132</dl>
133
134</dd>
135<dt><code>set tui tab-width <var>nchars</var></code></dt>
136<dd><a name="index-set-tui-tab_002dwidth"></a>
137<a name="index-tabset"></a>
138<p>Set the width of tab stops to be <var>nchars</var> characters.  This
139setting affects the display of TAB characters in the source and
140assembly windows.
141</p>
142</dd>
143<dt><code>set tui compact-source <span class="roman">[</span>on<span class="roman">|</span>off<span class="roman">]</span></code></dt>
144<dd><a name="index-set-tui-compact_002dsource"></a>
145<p>Set whether the TUI source window is displayed in &ldquo;compact&rdquo; form.
146The default display uses more space for line numbers and starts the
147source text at the next tab stop; the compact display uses only as
148much space as is needed for the line numbers in the current file, and
149only a single space to separate the line numbers from the source.
150</p></dd>
151</dl>
152
153<p>Note that the colors of the TUI borders can be controlled using the
154appropriate <code>set style</code> commands.  See <a href="Output-Styling.html#Output-Styling">Output Styling</a>.
