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. The maximum value for n is 255 or the
largest letter is JT. 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. If n is
omitted the the next chapter will be number 1. 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.

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.

.s.x NUMBER>LEVEL
sets the next header to the number specified.  If n is preceeded by
+#or#- the n is added or subtracted from the current value.  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.
Instead of a number n may be up to 2 letters.
The maximum value for n is 255 or the largest letter is JT.
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.

.s.tp5.i-5; _.NUMBER LIST [+-n]
.i-5; _.NMLS [+-n]
.s.x NUMBER>LIST
sets the next number in the list to n.  If n is preceeded by + or - then the
next list element number will be the current one + or - n.
If n is omitted the next element is numbered 1.
You may also specify a letter instead of n.  If this is done A corresponds
to 1, B to 2 and so on.
The maximum value for n is 3999.
If the current list element is numbered 10 and you specify _.NUMBER LIST +2
the the next element will be 12.

.SKIP 
starts page numbering if it had been stopped by _.NO NUMBER. If you wish to
pick the next page then specify n as the page number. n may also be a string
of up to 3 letters. If n is a letter A it corresponds to 1, B to 2, Z to 26.
Similarly AA is 27, AB 28 and so on. The maximum value for n is 3999. 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. If n is omitted the default is 1. The page number is
normally right justified with respect to the permanent right margin.  See the
_.PAGE SIZE command.
