Lists of items may be conveniently expressed in tabular form using the tab key
and the _.TAB STOPS command.  Every time you press the "tab" key you have
entered a tab into the text. Just as on a typewriter a tab will make the text
begin at the next tab stop. 
.ifnot small
The tab stops are set using the _.TAB STOPS
command.  You can right justify or center justify the items by specifying a 
right stop. When tabbing it is suggested that you use the _.NO JUSTIFY
command or the _.NO FILL command.  Having justification on will either give
you error messages, or cause unpredictable results. Remember that tab stops to
the left of the left margin are not effective. You should also _.DISABLE
HYPHENATION when using the tab feature.

This command clears all previous tabs, then sets new ones. Each n specifies
the column number for the tab stop That is n2 must be bigger than n1 and so
on. If a tab stop is +n then it will be n more than the previous one. If the
first stop is +n then it will be n more than the left margin. If the n is
prefaced by either R, C, or L then the text is right, center, or left
justified. If the number is preceeded by a literal then the text inside the
literal is used as an ellipses to fill in the space generated by the tab.

The maximum literal size is 15 characters.

.br;Sets up a series of stops every 10 columns with the first one 5 from
the left margin.
.i5;_.TAB STOPS 10,20,30,40,50

is at zero. 
.i5;_.TAB STOPS ". " L20,C25,R40

.p.x TAB>PROPORTIONAL
This sets tab stops to create n columns across a page between the left and
right margins. The first column begins at the left margin and ends at the
first tab stop. The second column begins at the first tab stop and ends at the
second one. The last one ends at the right margin. n must be 2 or larger. Tab
stops are set so that all unspecified columns have equal width. You specify
column 1 by specifying n1, column 2 by n2 and so on. When you omit a column it
is unspecified. If you specify a column as either + or -n then it is n larger
or smaller than the unspecified ones.  Using + or - you may increase or
decrease each column width from an evenly spaced one.  
.ifnot small
A column width may
not exceed 127. The actual number of tab stops set up is n-1.  So if you want
3 columns only 2 tab stops are set up. You may specify ellipses, and right or
left justification as in the _.TAB STOPS command.

For example you wish to set up 7
columns with 10 spaces in the second column, and 5 spaces in the 6'th column: 
.i5;_.TAB PROPORTIONAL 7,,10,,,,5
.br;Another example is to set up 7 columns with the first and last only
5 spaces wide to allow for indeted columns:
.i5;_.TAB PROPORTIONAL 7,5,,,,,,5
.br;This last example is a typical setup for a table.
Now if you set up your table and after looking at the result you
need to increase column 2 by 2 spaces
and decrease column 4 by 1 space you use:
.i5;_.TAB PROPORTIONAL 7,5,+2,,-1,,,5
.s;When this command is used all previously specified tab stops are
cleared.  This command is normally used instead of _.TAB STOPS for
evenly proportioning your columns.

.q  _.TAB RIGHT
.qq  _.TR
.p.x TAB>RIGHT
This causes the text following an unspecified tab to be right justified. This
command is the opposite of _.TAB LEFT.  The text is right justified at the
next tab terminator.  The text is considered to be terminated by either a
space, tab, end of line, break character, or autobreak character.  
.ifnot small
If the
break character is used to define the right side of the text, then the _.FLAGS
BREAK command must be issued. This allows typing tables with the text right
justified, or with an arbitrary point (defined by the break) lined up.

You may wish to set up a series of tab stops to produce a list of items.
If no item needs to go in any particular column you may produce the
desired effect by setting _.FILL _.NO JUSTIFY.  Each item may be preceeded
by a tab.  If you wish the left hand column to line up with the left margin
use _.NO KEEP TABS.  Otherwise the first column will line up on the first tab
stop.
