PATHNAME 
(sometimes referred to as a PATH)

A pathname is a series of one or more directory names separated by the \ 
special character. It may begin with a \ if the pathname begins in root, or 
begin with a directory name, if the pathname begins in the current directory. 
A pathname cannot be more than 63 characters long.

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

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


     In the sample disk structure above we have:

Pathnames:				Pathnames relative to TESTS:
\					.
\PROJECTS				..
\TESTS					DONE
\TESTS\DONE				PENDING
\TESTS\PENDING				PENDING\RESULTS
\TESTS\PENDING\RESULTS			..\PROJECTS
\BUDGETS				..\BUDGETS
