DIRECTORY




 >>--DIRECTORY(--+--------------+-)---------><
                 +-newdirectory-+

DIRECTORY returns the current directory, first changing it to newdirectory 
if an argument is supplied and the named directory exists. 
The return string includes a drive letter prefix as the first two 
characters of the directory name. Specifying a drive letter prefix as part 
of newdirectory causes the specified drive to become the current drive. If 
a drive letter is not specified, then the current drive remains unchanged. 

For example, the following program fragment saves the current directory 
and switches to a new directory; it performs an operation there, and then 
returns to the former directory. 

/* get current directory */
curdir = directory()
/* go play a game */
newdir = directory("d:/usr/games")
if newdir = "d:/usr/games" then
   do
   fortune  /* tell a fortune */
/* return to former directory */
   call directory curdir
   end
else
   say 'Can't find /usr/games'
