Syntax
Diagrams
At the beginning
of
each of the following chapters are
syntax
diagrams
showing the proper syntax for each command.
All
characters contained in
a
circle or oblong are literals, and must be entered exactly
as shown.
Words and
phrases
contained in
rectangles are names of
items used
with
the command and are described in the accompanying text of
each
command. Each line can only be entered from one direction
as
indicated
by the arrow on the entry
line.
Any combination
of
commands and
arguments that can be generated
by following
the lines in the proper
direction
is syntactically
correct.
An
argument
is
optional
if
there
is
a
path around
it.
Where there
is
a
rectangle which contains the
word
"space"
a
white
space
character must be entered.
White
space
is
optional
in many other places.
