causes a BREAK and an advance to a new page. 
If the current page is empty, a page advance is not performed.
.ifnot small
Like an automatic page advance, this command prints the title (if given)
and page numbers on every page. The next page number can be selected
with the _.NUMBER command.  This command is illegal during a footnote or note.

produces a new page, but the page number is unchanged and letters are
appended to the page number until an _.END PAGE command is encountered.
.ifnot small
This command permits the insertion of additional pages within 
an existing document without changing the existing page numbering.
Subpages can be renumbered with the _.NUMBER SUBPAGE command.
While subpaging is in effect, _.TEXT commands are illegal.
Deferred text is never printed on subpages.
.p;For example, if you are on page 5 and _.SUBPAGE is used, a page numbered
5A will be produced.  Subsequent pages will be numbered 5B, 5C and so on.
After an _.END SUBPAGE, the next page number will be 6.

.ifnot small
When no paging is in effect, neither footnotes nor text sections are
allowed, but a new page can be produced with the _.PAGE command.
_.CHAPTER, _.APPENDIX, or _.PAGE SIZE commands will enable paging. 
These commands are illegal inside a note, footnote, or text section.

specifies a text section that is to be kept all on one page.
The text section is ended by a _.PAGE, _.END TEXT, or another _.TEXT command.
.ifnot small
If the text section is too long to fit on the current page, the rest of the
current page will be blank and the section will begin at the beginning of the
next page. With this command you can guarantee that a given section of text
will not be split between 2 pages unless it is too long to fit on 1 page. If a
_.PAGE command terminates a section, the rest of the page after the
section will be blank. This command is illegal inside a footnote, note, or
subpage. Likewise, footnotes and _.TEST PAGE, _.TEST TEXT, or _.FIGURE
DEFERRED are illegal inside this command. This command causes a break.

.q  _.TEXT DEFERRED

.p .x TEXT>DEFERRED
starts a text section that will be printed later if it doesn't fit on
the current page.  The normal _.TEXT command leaves the bottom of the
current page blank if the text section doesn't fit. The _.TEXT DEFERRED
command will save the text for printing on later pages if necessary.
If text is deferred, the current page will be filled with the text that
follows the next _.END TEXT or _.PAGE command.
.ifnot small
The deferred text section is terminated by a _.TEXT, _.TEXT DEFERRED,
_.END TEXT, or _.PAGE command. Several deferred sections can be defined
at one time; they will appear on later pages as necessary.
The _.TEXT DEFERRED command is useful for defining figures with captions. 
If the page length is changed in the middle of the document, deferred pages
might not appear correctly, since the decision to defer the text is based on
the original page size.
This command causes a break.
.HELPD	NOTE
.note
_.TEXT DEFERRED does not modify the rules applicable to the _.SKIP, _.FIGURE
and _.BLANK commands.  If a _.SKIP command follows the _.TEXT command
and the text appears at the top of a page, the _.SKIP command is ignored.
This will cause trouble when a _.TEXT DEFERRED is followed by _.PAGE.
If _.SKIP follows the _.TEXT DEFERRED, it will be ignored and
the text will be shortened with the result that the intended
text will not fill the page, and regular lines might appear at the bottom of
the page.  If you need to skip lines after _.TEXT, you should use
the _.FIGURE command to reserve exactly the space you need.

If a _.PAGE command is issued with deferred text pending, you are not

guaranteed by issuing several page commands in a row, but a better way
of forcing a blank page is

.q _.TEST PAGE  [t] [,b] 
.qq   _.TP [t] [,b]
.p.x TEST>PAGE
causes a BREAK followed by a conditional page advance. If there are fewer
than t lines left on the page, an advance to the next page is performed.
When you specify b, test page operates slightly differently:
the text following the test page  up to the next command that causes a break
is treated as a block.  Thus, b is useful in preventing orphan lines.
t specifies the minimum number of lines at the
top of the block and b the minimum number of lines at the bottom.
.ifnot small
The text will be arranged to maintain the minimum number of lines/page.
In other words, the first t lines will all be on the same page, and the last
b lines will also all be on a single page.  The first t lines might not 
necessarily be on the same page with last b lines.

is useful if you wish to test for sufficient space on the current page
without breaking the line.
