The <STRONG>tabs</STRONG> program clears and sets tab-stops on the termi-
nal. This uses the terminfo <EM>clear</EM><STRONG>_</STRONG><EM>all</EM><STRONG>_</STRONG><EM>tabs</EM> and <EM>set</EM><STRONG>_</STRONG><EM>tab</EM>
capabilities. If either is absent, <STRONG>tabs</STRONG> is unable to
clear/set tab-stops. The terminal should be configured to
use hard tabs, e.g.,
- stty tab0

increasing numeric order, and greater than zero. They are
separated by a comma or a blank, for example,
