Introduction

    The DEBUG program can be used to:

    ■   Provide a controlled testing environment so you can monitor and
        control the execution of a program to be debugged. You can fix
        problems in your programs directly, and then execute the program
        immediately to determine if the problems have been resolved. You
        do not need to reassemble a program to find out if your changes
        worked.

    ■   Load, alter, or display any file.

    ■   Execute object files. Object files are executable programs in
        machine language format.
