-abc = fs.list("")    <- will get all the files and directories in the system root into a table, all saved as 'abc'.
-i = 1                <- sets i equal to one.
-while i ~= 15 do    <- While i is not 15, continue to do this.
-print(abc[i])        <- print the files and directories.
-i = i+1              <- add 1 to i each run so a different file/directory gets listed next.
-end                  <- end the loop.
-this code will print 15 lines, blank or not, with the contents of the root directory.
