+.Sh DESCRIPTION
+The
+.Nm
+utility displays a series of characters that first clears the hardware terminal
+tab settings and then initializes the tab stops at the specified positions
+and optionally adjusts the margin.
+.Pp
+The phrase "tab-stop position N" means that, from the start of a line of
+output, tabbing to position N shall cause the next character output to be in
+the (N+1)th column on that line.
+.Pp
+The following options are supported:
+.Bl -tag -width Fl
+.It Fl Ar n
+Specifies repetitive tab stops separated by a uniform number of columns,
+.Ar n ,
+where
+.Ar n
+is a single digit decimal number.
+The default usage of
+.Nm
+with no arguments is equivalent to
+.Nm
+.Fl 8 .
+When
+.Fl 0
+is used, the tab stops are cleared and no new ones set.
+.It Fl a
+Assembler, applicable to some mainframes.
+Equivalent to
+.Nm
+1,10,16,36,72 .
+.It Fl a2
+Assembler, applicable to some mainframes.
+Equivalent to
+.Nm
+1,10,16,40,72
+.It Fl c
+.Tn COBOL ,
+normal format.
+Equivalent to
+.Nm
+1,8,12,16,20,55
+.It Fl c2
+.Tn COBOL ,
+compact format (columns 1 to 6 omitted).
+Equivalent to
+.Nm
+1,6,10,14,49
+.It Fl c3
+.Tn COBOL ,
+compact format (columns 1 to 6 omitted), with more tabs than
+.Fl c2 .
+Equivalent to
+.Nm
+1,6,10,14,18,22,26,30,34,38,42,46,50,54,58,62,67

+.It Fl s
+.Tn SNOBOL .
+Equivalent to
+.Nm
+1,10,55
+.It Fl T Ar type
+Indicates the type of terminal.
+.It Fl u
+Assembler, applicable to some mainframes.
+Equivalent to
+.Nm

+.El
+.Sh ENVIRONMENT
+The
+.Ev COLUMNS
+and
+.Ev TERM
+environment variables affect the execution of
+.Nm
+as described in
+.Xr environ 7 .
+.Pp
+The
+.Fl T
+option overrides
+.Ev TERM .
+If neither
+.Ev TERM
+nor the
+.Fl T
+option are present,
+.Nm
+will fail.
+.Sh EXIT STATUS

+.Sh STANDARDS
+The
+.Nm
+utility conforms to
+.St -p1003.1 .
+.Sh HISTORY
+A
+.Nm
+utility first appeared in PWB UNIX.
+This implementation was introduced in
+.Nx 6.0 .
