PART 7
USING MS-DOS
7.6.3 Drive Designation
In addition to the file name and the file name
extension, the name of your file may include a drive
designation. The drive designation is a letter and a
colon, such as A: or B:. This tells MS-DOS where the
file is.
The file name and extension immediately follow the
drive designation. For example,
A: BUDGET
B: PROG I.BAS
If you use a file name without the drive designation,
as in
BUDGET
MS-DOS assumes that the file is located in the current
(or default) disk drive.
