Specifying the Drive Designator If you want to access a program or file on another drive without first changing the default drive, type the drive designator along with the filename. For example, if you are logged onto drive A and want to use a file named PROGRAM on drive C, you would type the following and then press Enter: C:PROGRAM MS-DOS loads and executes the file named PROGRAM from drive C, but stays logged onto drive A. Types of MS-DOS Commands Each MS-DOS command is either internal or external. Internal commands are commands that are built into MS-DOS and can be used at any time once MS-DOS is loaded into memory. External commands are separate program files stored on your hard disk and MS-DOS diskettes. If you display a directory of the files on your MS-DOS diskettes, you see the names of the external commands but not the internal ones. The following lists show which external commands are on which diskette. Startup diskette ANSI.SYS COMMAND.COM COUNTRY.SYS DISPLAY.SYS DRIVER.SYS EGA.CPI FASTOPEN.EXE FDISK.COM FORMAT.COM KEYB.COM KEYBOARD.SYS MODE.COM NLSFUNC.EXE PRINTER.SYS REPLACE.EXE SELECT.COM SYS.COM VDISK.SYS XCOPY.EXE 4201.CPI Using MS-DOS With Your Computer 4-5
