These are the parameters which may appear at any point within the
Contents Page:

%SubDir=pathname
%Editor=pathname
%FormDepth=number
%PagingLevel=number

Note that no space characters may appear anywhere in a parameter
line. Any alphabetic character may be either upper or lower
case.

%SubDir specifies the name of the DOS subdirectory in which MANUAL
is to create or look for the text files of the current document. By
default, MANUAL will search only the current directory.

e.g., %SubDir=mybook

      causes MANUAL to look for the text files of the current
      document in subdirectory MYBOOK of the current directory.

      %SubDir=c:\mybooks\book3

      causes MANUAL to look for the text files of the current
      document in directory C:\MYBOOKS\BOOK3

%Editor specifies the name of the Editor or Word Processor which is
to be invoked when the current document's text files are edited
within MANUAL.

By default, MANUAL will call the default Editor whose name is stored
in the MANUAL configuration file. If no default Editor has been set
up then MANUAL will ask you to enter a name when you first try to
edit a text file belonging to a document which has no %editor line
in its Contents Page.

e.g., %Editor=c:\utils\myprog.exe

%FormDepth specifies how many lines are required per page when
printing the current document. By default, 60 lines are printed per
page.

e.g., %FormDepth=40

      causes MANUAL to print no more than 40 lines per page.

%PagingLevel specifies the subsection level, relative to the topmost
level being printed, above which subsections must start on a new
page.

No matter what %PagingLevel is specified, MANUAL always starts a new
page if there are less than eight lines left on the current page
when a new subsection is encountered.

e.g., %PagingLevel=0

      tells MANUAL never to issue a page throw at start-of-subsection,
      unless it happens to be necessary because of the eight line
      rule.

      %PagingLevel=1

      This is the default. It specifies that only the topmost level
      being printed should cause an automatic page throw.
