  60        The  <STRONG>tabs</STRONG>  program clears and sets tab-stops on the termi-
  61        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>
  62        capabilities.   If  either  is  absent,  <STRONG>tabs</STRONG> is unable to
  63        clear/set tab-stops.  The terminal should be configured to
  64        use hard tabs, e.g.,
  65
  66               stty tab0

  75             Tell <STRONG>tabs</STRONG> which terminal type to use.  If this option
  76             is not given, <STRONG>tabs</STRONG> will  use  the  <STRONG>$TERM</STRONG>  environment
  77             variable.   If  that  is  not  set,  it  will use the
  78             <EM>ansi+tabs</EM> entry.
  79
  80        <STRONG>-d</STRONG>   The debugging option shows a ruler line, followed  by
  81             two  data  lines.   The  first  data  line  shows the
  82             expected tab-stops marked with asterisks.  The second
  83             data  line  shows  the  actual tab-stops, marked with
  84             asterisks.
  85
  86        <STRONG>-n</STRONG>   This option tells <STRONG>tabs</STRONG> to check the options  and  run
  87             any  debugging option, but not to modify the terminal
  88             settings.
  89
  90        <STRONG>-V</STRONG>   reports the version of ncurses which was used in this
  91             program, and exits.
  92
  93        The  <STRONG>tabs</STRONG>  program  processes  a single list of tab stops.
  94        The last option to be processed which defines  a  list  is
  95        the one that determines the list to be processed.
  96

  98 </PRE>
  99 <H3><a name="h3-Implicit-Lists">Implicit Lists</a></H3><PRE>
 100        Use  a  single number as an option, e.g., "<STRONG>-5</STRONG>" to set tabs
 101        at the given interval (in this case  1,  6,  11,  16,  21,
 102        etc.).   Tabs  are  repeated up to the right margin of the
 103        screen.
 104
 105        Use "<STRONG>-0</STRONG>" to clear all tabs.
 106
 107        Use "<STRONG>-8</STRONG>" to set tabs to the standard interval.
 108
 109
 110 </PRE>
 111 <H3><a name="h3-Explicit-Lists">Explicit Lists</a></H3><PRE>
 112        An explicit list can be defined after  the  options  (this
 113        does  not  use  a "-").  The values in the list must be in
 114        increasing numeric order, and greater than zero.  They are
 115        separated by a comma or a blank, for example,
 116
 117               tabs 1,6,11,16,21
 118               tabs 1 6 11 16 21
 119        Use  a  '+'  to treat a number as an increment relative to
 120        the previous value, e.g.,
 121
 122               tabs 1,+5,+5,+5,+5
 123
 124        which is equivalent to the 1,6,11,16,21 example.

 129        X/Open defines several predefined lists of tab stops.

 152        X/Open describes a <STRONG>+m</STRONG> option, to set  a  terminal's  left-
 153        margin.   Very few of the entries in the terminal database
 154        provide this capability.
 155
 156        The <STRONG>-d</STRONG> (debug) and <STRONG>-n</STRONG> (no-op) options are  extensions  not
 157        provided by other implementations.
 158
 159        Documentation  for other implementations states that there
 160        is a limit on the number of tab stops.  While some  termi-
 161        nals may not accept an arbitrary number of tab stops, this
 162        implementation will attempt to set tab  stops  up  to  the
 163        right  margin  of the screen, if the given list happens to
 164        be that long.
