       tabs - set tabs on a terminal

       tabs  [	-n  | --file [ [-code] | -a | -a2 | -c | -c2 | -c3 | -f	| -p |
       -s | -u]	]  [ +m	[n]] [-T type]

       tabs [-T	type] [	+ m [n]] n1 [ ,	n2 ,...]

       tabs sets the tab stops on the user's terminal according	to a tab spec-
       ification,  after  clearing  any	previous settings. The user's terminal
       must have remotely settable hardware tabs.

       The following options are supported. If a given flag occurs  more  than
       once, the last value given takes	effect:

       -T type
	     tabs  needs to know the type of terminal in order to set tabs and
	     margins. type is a	name listed in term(5).	 If no -T flag is sup-
	     plied,  tabs  uses	the value of the environment variable TERM. If
	     the value of TERM is NULL or TERM is not defined in the  environ-
	     ment  (see	 environ(5)), tabs uses	ansi+tabs as the terminal type
	     to	provide	a sequence that	will work for many terminals.

       +m[n] The margin	argument may be	used for some terminals. It causes all
	     tabs  to  be  moved  over n columns by making column n+1 the left
	     margin.  If +m is given without a value of	n, the	value  assumed
	     is	 10. For a TermiNet, the first value in	the tab	list should be
	     1,	or the margin will move	even further to	the right. The	normal
	     (leftmost)	 margin	on most	terminals is obtained by +m0. The mar-
	     gin for most terminals is reset only when the +m  flag  is	 given

   Tab Specification
       Four  types  of tab specification are accepted.	They are described be-
       low: canned, repetitive (-n), arbitrary (n1,n2,...), and	file (-file).

       If no tab specification is given, the default value  is	-8,  that  is,
       UNIX  system  ``standard''  tabs.  The lowest column number is 1. Note:
       For tabs, column	1 always refers	to the leftmost	column on a  terminal,
       even  one  whose	 column	markers	begin at 0, for	example, the DASI 300,
       DASI 300s, and DASI 450.

   Canned -code
       Use one of the codes listed below to select a canned set	 of  tabs.  If
       more  than  one	code  is specified, the	last code option will be used.
       The legal codes and their meanings are as follows:

       -a    1,10,16,36,72 Assembler, IBM S/370, first format

       -a2   1,10,16,40,72

	     Assembler,	IBM S/370, second format

       -c    1,8,12,16,20,55

	     COBOL, normal format

       -c2   1,6,10,14,49

	     COBOL compact format (columns 1-6 omitted). Using this code,  the
	     first  typed  character  corresponds  to card column 7, one space
	     gets you to column	8, and a tab reaches column  12.  Files	 using
	     this  tab	setup should include a format specification as follows
	     (see fspec(4)):

		    <:t-c2 m6 s66 d:>

       -c3   1,6,10,14,18,22,26,30,34,38,42,46,50,54,58,62,67

	     COBOL compact format (columns 1-6 omitted), with more  tabs  than
	     -c2.  This	 is  the recommended format for	COBOL. The appropriate
	     format specification is (see fspec(4)):

		    <:t-c3 m6 s66 d:>

       -f    1,7,11,15,19,23


       -p    1,5,9,13,17,21,25,29,33,37,41,45,49,53,57,61


       -s    1,10,55


       -u    1,12,20,44

	     UNIVAC 1100 Assembler

       -n    A repetitive specification	requests tabs at columns  1+n,	1+2*n,
	     etc., where n is a	single-digit decimal number. Of	particular im-
	     portance is the value 8: this represents the UNIX system  ``stan-
	     dard''  tab  setting,  and	 is  the most likely tab setting to be
	     found at a	terminal. When -0 is used, the tab stops  are  cleared
	     and no new	ones are set.

       See OPERANDS.

       -file If	 the name of a file is given, tabs reads the first line	of the
	     file, searching for a format specification	(see fspec(4)).	If  it
	     finds one there, it sets the tab stops according to it, otherwise
	     it	sets them as -8. This type of specification  may  be  used  to
	     make  sure	 that  a  tabbed file is printed with correct tab set-
	     tings, and	would be used with the pr command:

	     example% tabs - file; pr file

       Tab and margin setting is performed via the standard output.

       The following operand is	supported:

		    The	arbitrary format consists of tab-stop values separated
		    by	commas or spaces. The tab-stop values must be positive
		    decimal integers in	ascending order. Up to 40 numbers  are
		    allowed.  If any number (except the	first one) is preceded
		    by a plus sign, it is taken	as an increment	to be added to
		    the	 previous  value.  Thus,  the  formats 1,10,20,30, and
		    1,10,+10,+10 are considered	identical.

       Example 1: Using	the tabs Command

       The following command is	an example using -code ( canned	specification)
       to  set tabs to the settings required by	the IBM	assembler:  columns 1,
       10, 16, 36, 72:

       example%	tabs -a

       The next	command	is an example of using -n (repetitive  specification),
       where  n	 is  8,	 causes	tabs to	be set every eighth position: 1+(1*8),
       1+(2*8),	... which evaluate to columns 9, 17, ...:

       example%	tabs -8

       This command uses n1,n2,... (arbitrary specification) to	 set  tabs  at
       columns 1, 8, and 36:

       example%	tabs 1,8,36

       The  last  command is an	example	of using -file (file specification) to
       indicate	that tabs should  be  set  according  to  the  first  line  of
       $HOME/fspec.list/att4425	 (see fspec(4)).

       example%	tabs -$HOME/fspec.list/att4425

       See  environ(5) for descriptions	of the following environment variables
       that affect the execution of tabs: LC_CTYPE, LC_MESSAGES, and NLSPATH.

       TERM  Determine the terminal type.  If this variable is unset or	 null,
	     and  if  the  -T option is	not specified, terminal	type ansi+tabs
	     will be used.

       The following exit values are returned:

       0     Successful	completion.

       >0    An	error occurred.

       See attributes(5) for descriptions of the following attributes:

       |      ATTRIBUTE	TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWcsu			   |
       |CSI			     |enabled			   |

       expand(1), newform(1), pr(1), stty(1), tput(1), fspec(4),  terminfo(4),
       attributes(5), environ(5), term(5)

       There  is  no  consistency  among different terminals regarding ways of
       clearing	tabs and setting the left margin.

       tabs clears only	20 tabs	(on terminals requiring	a long sequence),  but
       is willing to set 64.

       The  tabspec  used with the tabs	command	is different from the one used
       with the	newform	command. For example, tabs -8 sets every eighth	 posi-
       tion; whereas newform -i-8 indicates that tabs are set every eighth po-
