Line 70 Calls the subprogram to display the list of the files in the current
directory.
Lines 160 to 200 Check the storage device currently selected and its current directory
name, and then display the result.
Lines 230 to 240 Check the number of the files in the current directory.
Lines 250 to 330 If there are any files in the current directory, check the name and size
of every file and display them.
The following is the output result of the program, assuming that the selected storage device
is the Ram disk and the current directory, \TEST, contains 2 files, FILE1.STA (size: 24576
bytes) and FILE2.TIF (size: 16384 bytes) and 1 directory, DIR1. For size of a directory, -1
is displayed. To view the list of the files in DIR1, use the CHAD' command to change the
current directory to DIR1 and then execute this program again.
