Assume that some of the directories on hard disk C: were as 
follows:

		     C:			ROOT DIRECTORY
		 ---------
		/    |    \
	       /     |     \
	      /      |      \
	     /       |       \
	 PROJECTS  TESTS   BUDGETS	SUBDIRECTORIES
		   -----
		  /     \
		 /       \		   additional
	      DONE      PENDING		SUBDIRECTORIES


     In the sample disk structure above we have subdirectories 
PROJECTS, TESTS, BUDGETS, DONE, and PENDING.  

SAMPLE command to use PATH     | Comments about the output

  APPEND C:\PROJECTS;C:\TESTS\DONE This command instructs DOS to search the
				 PROJECTS and TESTS\DONE directories for 
				 an input file that is needed by a command
				 but is not in the current directory. If
				 APPEND had previously been executed,
				 these directories would be added to the
				 existing path.

  APPEND ;			This is how you reset the path back to
				the current directory only.

  APPEND			To see what directory paths are
No appended directories		currently specified, simply type APPEND
				with no options.  In this case, there
				are no directories to be searched other
				than the current directory.

				If you use this command when you first
  APPEND \			start your computer, the root directory
				in the current disk drive (that hopefully
				contains DOS and the external commands)
				will always be searched, no matter what 
				your current directory is. \ stands for 
				the root directory.
