**CIGAL Reference Manual, Chapter 2 (Commands): MANUAL**
===== MANUAL -- Format HELP information in a form suitable for printing =====
** usage: manual subject [linenumber]      (to print out help information)**\\
**    or: manual entrynumber               (to print the ENTRYNUMBERth entry in the help file)**

The MANUAL command is virtually identical to the HELP command, except
that a header is printed at the top of each page.  MANUAL is intended to
be used for printing HELP topics in a form suitable for a generating a
printed user's manual.

MANUAL finds information in the help file either by topic name or by
entry number.  Specifying entries by number is a useful way of printing
many help entries in succession.  To print entries by entry number, MANUAL's
first argument must be an explicit number, or an expression that evaluates
to a number.  A number variable on its own will be treated as a topic name.

If MANUAL can find the specified entry it returns the value 0 in number
register 0 (#0).  If MANUAL cannot find the entry it returns -1 in #0.

The following example illustrates how to print the entire manual:
          #1 = 0
          while(1) {
                  manual #1++             ; #1++ is treated as an expression
                  if(#0 < 0) return
          }
