.SH NAME
\fB\%@TABS@\fP \-
set terminal tab stops
This uses the terminfo \fBclear_all_tabs\fP and \fBset_tab\fP capabilities.
If either is absent, \fB@TABS@\fP is unable to clear/set tab-stops.
The terminal should be configured to use hard tabs, e.g.,
-.NS
+.PP
+.RS 4
+.EX
stty tab0
-.NE
+.EE
+.RE
.PP
Like \fB@CLEAR@\fP(1), \fB@TABS@\fP writes to the standard output.
You can redirect the standard output to a file (which prevents
database, the result is unpredictable.
Before running curses programs,
you should either reset tab-stops to the standard interval
-.NS
-tabs -8
-.NE
+.PP
+.RS 4
+.EX
+tabs \-8
+.EE
+.RE
.PP
or use the \fB@RESET@\fP program,
since the normal initialization sequences do not ensure that tab-stops
The values in the list must be in increasing numeric order,
and greater than zero.
They are separated by a comma or a blank, for example,
-.NS
+.PP
+.RS 4
+.EX
tabs 1,6,11,16,21
-.br
tabs 1 6 11 16 21
-.NE
+.EE
+.RE
.PP
Use a \*(``+\*('' to treat a number
as an increment relative to the previous value,
e.g.,
-.NS
+.PP
+.RS 4
+.EX
tabs 1,+5,+5,+5,+5
-.NE
+.EE
+.RE
.PP
which is equivalent to the 1,6,11,16,21 example.
