Part 1: Loading the DEBUG Program Here we willlearn how to bring up the DEBUG program from the keyboard of the PC. The laboratory procedures the follow assume that the PC has a floppy disk driver called A and a hard disk, drive C; that is, either a PCXT or PCAT is in use. It is also assumed that the DOS directory on drive C contains the DEBUG.EXE program and that the path is set to this directory. Procedure 1. Turn on the PC, enter the DOS operating system environment. 2. Load DEBUG by issuing the command C:DOS>DEBUG()) What prompt do you see on the screen? 3. Return to the DOS operating system by entering the command What prompt is now displayed
