1      A command line is a line containing a "command" and any "arguments" that
 2 go with the command, each separated by one or more blank spaces.  It is always
 3 concluded by a carriage return.  For example:
 4 
 5 list my_segment -name
 6 
 7 is a command line.  It invokes the list command to list the "pathname"
 8 my_segment.  It uses the "control argument" -name to specify that only the
 9 names assigned to my_segment are to be listed and none of the other
10 information that is normally listed.

12      When a command takes several arguments, the order in which the arguments
13 are typed is often significant.  Normally, pathname arguments follow
14 immediately after the command name and control arguments follow them.  But
15 there are exceptions. Then there are commands that accept more than one
16 pathname, and the order in which they appear is usually significant.  There
17 are also other types of arguments that may appear on a command line, and these
18 must be placed properly.  For these reasons it is wise to check the command
19 description when you are uncertain about the order of arguments for a command.

21      A command line may consist of more than one command.  See the Multiple
22 Commands option in this menu.
