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
}
