These commands set numbers for various items.  The number may be 
either a decimal number or a string of letters.
If n is a letter A it corresponds to 1, B to 2, Z to 26,
AA to 27, AB to 28, and so on.
If the number is preceded by a plus sign "+" then then new value is the old
value plus the specified increment.  If the number is omitted it is assumed
to be 1.  No number may exceed 3999 or
EWU.  DSR allows larger numbers, but incorrectly handles Roman numerals larger
than 3999.

.p.x NUMBER>CHAPTER 
supplies a number (n) to be used in a subsequent  CHAPTER  command. NUMBER
CHAPTER  would be used when a chapter of a document occupies a source file of
its own.  In such  a case,  NUMBER CHAPTER  would be the first command of the
source file. n may also be a letter. 
This would also be used if you wish to skip a chapter
for insertion later on.  To skip chapters specify +n. If the current chapter
is 10 and you specify _.NUMBER CHAPTER +2 the next chapter will be 12.
This command also enables
chapter numbering.  When chapter numbering is in effect each _.CHAPTER or
_.APPENDIX command resets the page number to 1 and the chapter or appendix
number are printed with the page number as part of the page header.  This is
the normal RUNOFF mode.

.q  _.NO NUMBER CHAPTER 
.p.x NO>NUMBER CHAPTER 
disables chapter numbering.  When it is disabled, the page numbers are not
reset with each chapter or appendix, and the chapter/appendix number is not
printed as part of the header. 
This command must be issued before the first
_.CHAPTER or _.APPENDIX command if you wish to disable chapter-page numbering.
In addition it must be reissued after each _.NUMBER CHAPTER if you intend to
control chapter numbering but wish running page numbers. 
You may permanently disable chapter numbering with _.DISABLE NUMBERING 
CHAPTER.

.p.x NUMBER>LEVEL
sets the next header to the number specified.  
The next
time _.HEADER LEVEL is used the number specified will be the header number.
If the next _.HEADER LEVEL command specifies a level different from
the one implied in the _.NUMBER LEVEL command the result will be undefined.
If n1 is omitted then the next level will be 1.0.
For example the following command sequence is specified:
.s.i10; _.NUMBER HEADER 5,4,3,2 _.HEADER LEVEL
.s
The result of this would be:
.s.i10; 5.4.3.2
.br;If the current level is 1.2.3.4 and _.NUMBER LEVELS +1,+1,-1,-1
is specified, then the next section header will be 2.3.2.3.
.helpd ITEM

sets the next number in the list to n.

the the next element will be 12.

.p.x NUMBER>PAGE 
These commands control page numbering. If you wish to pick the next page then
specify n as the page number. If you
wish to skip several pages for inserting diagrams, artwork or any other items
which require a full pages, you may do so by issuing the following commands: 
.i5; _.NUMBER PAGE +n _.PAGE 
The next page number will be the current page number +n. If you issue _.NUMBER
PAGE 10 then the next page will be 10. If the current page is 10 and you
specify _.NUMBER PAGE +2 the next page will be 12. If the current page is 10
and you specify _.NUMBER PAGE -1, the next page will be 9.  _.NUMBER PAGE +1
essentially is redundant.  The page number is
normally right justified with respect to the permanent right margin.  See the
_.PAGE SIZE command. 
.p
_.NO NUMBER PAGE stops page numbering. However, pages continue to be counted,
so that the normal page number can appear if page numbering is resumed with
the  _.NUMBER command. If you wish to disable page numbering so that the
_.NUMBER command will not enable it you should use _.DISABLE NUMBERING. 
.helpd SUBPAGE
