Starting Debug
Method 1
How to Start Debug
Debug may be started two ways. By the first method, you type all
commands in response to the debug prompt (a hyphen). By the r-, ..
second method, you type all commands on the line used to start L
debug.
Method 1: debug
Method 2:
debug [filename [arglistll
Method 1: Debug
To start debug using method 1, simply type the following:
debug
Debug responds with the hyphen (-) prompt, signaling that it is
ready
to accept your commands. Since you didn't specify a file-
name,
you can use other commands to work on current memory,
disk sectors,
or disk files.
Warnings
• When debug (version 2.0) is started, it sets up a program
header at offset 0 in the program work area. In previous ver-
sions
of debug, you could overwrite this header. You can still
overwrite the default header if you don't give a filename to
debug. If you are debugging a . com or .exe file, however, do
not tamper with the program header below address 5CH, or
debug will terminate.
• Do
not restart a program after the following message is
displayed:
Program terminated normally
You must reload the program with the N (name) and L (load)
commands for it to run properly.
