    The following information applies to all DEBUG commands:

    .   A command is a single letter, usually followed by one or
        more parameters.

    .   Commands and parameters can be entered in uppercase or
        lowercase, or a combination of both.

    .   Commands and parameters may be separated by delimiters.
        Delimiters are only required, however, between two con-
        secutive hexadecimal values.
        Thus, these commands are equivalent:

        dcs:100 110
        d cs:100 110
        d,cs:100,110

    .   Press Ctrl-Break to end commands.

    .   Commands become effective only after you press the Enter
        key.

    .   For commands producing a large amount of output, you can
        press Ctrl-NumLock (or Pause) to suspend the display to
        read it before it scrolls away. Press any other character
        to restart the display.

    .   You can use the control keys and the DOS editing keys
        while using the DEBUG program.

    .   If a syntax error is encountered, the line is displayed
        with the error pointed out as follows:

        d cs:100 CS:110
                  ^error

        In this case, the Dump command is expecting the second
        address to contain only a hexadecimal offset value. It
        finds the S, which is not a valid hex character.

    .   The prompt from the DEBUG program is a hyphen (-).
