    The debug command it is sent to is used to test parts of your computer and interact with the code to perform specific tasks on your computer.

    The DEBUG line debugger is a great new command outside of operating systems such as DOS, OS / 2, and Windows (16-bit / 32-bit only [1] ).

    What happened to DOS debug?

    Although the technical documentation available for the DEBUG command was removed with the release of MS / DOS 3.3, the command is currently retained in the current distribution, unlike EXE2BIN.

    DEBUG can act when an assembler or hexadecimal disassembler program allows users to interactively parse the contents of memory (assembly language, hexadecimal, ASCII), make changes, and unambiguously execute COM, EXE, and other types of documents. It also has several subcommands that are used to access allocated disk sectors, I / O ports, and memory addresses.

    Overview

    Traditionally, all computers and operating resources include a service function thatused to determine if the work schedule is correct. [citation needed] DEBUG was originally written by Tim Paterson to run on 86-DOS. When Paterson joined Microsoft in the early 1980s, he brought this product with him. DEBUG was most commonly associated with DOS 1.00 and was used in MS-DOS / PC-DOS and some Microsoft Windows replicas. Originally known as DEBUG. Org, the executable has been renamed DEBUG.EXE and DOS 5.0. [2]

    Windows XP and later include DEBUG for the MS-DOS Subsystem for MS-DOS compatibility. 16-bit DOS commands are not available on 64-bit editions of Windows. [3]

    • Only 8086 opcodes are supported in assembler / disassembly methods.
    • Most likely it will only access 16-bit registers, as well as 32-bit non-extended registers.
    • If the “N” subcommand is used to name files, this file name will be stored in DS: 5D – DS: 67 (program segment prefix file control block area). This means that the program can only save data in FAT 8.3. – File name format.

    DEBUG Extended Packages Containspress debug command in Novell DOS 7, OpenDOS 7.01 with DR-DOS 7.02 and newer, new implementation of the old SID / SID86 symbolic instruction debugger from Digital Research, [4] something came with the old version of DR DOS … [5] [6] [7] It is fully compatible with DEBUG string syntax – Aber ms-dos / pcdos allows many improvements, including including support for 16-bit or 32-bit opcodes up to Pentium, extended mode (/ X) with a whole set of commands and additional sub-modes, they just greatly improved the command line syntax with custom macros and symbolic debug centers with named registers loaded with symbolic information , basic math operations and transformations, with alignment disassembler and comments. [8] [7] Some versions also used the DPMS function as the “S tealth mode” protected mode debugger. [9]

    The FreeDOS version of DEBUG was compiled by Paul Voyta and listed below under the MIT license. 32 bits [10]

    There is also a copy of the “DEBUGX” version that supports the 32-bit DPMI business interface. [11] Andreas “Jaff t »Grech, the author of the HX-DOS extender, improved on DEBUG solutions developed from version 0.98 to 1.25, and former PC-DOS engineer Vernon S. Brooks added 1.26 styles to 1.32. [12]

    Syntax

     DEBUG [[drive:] [path] filename [settings]] 

    If DEBUG is started with no parameters, a specific DEBUG prompt, “-“, appears. The user can then enter a subcommand associated with one or two letters using “A” for input-assembly method, “D” for a one-time hexadecimal number, “T” for tracing, and “U” for disassembly (disassembly). ) a program that uses memory. [13] DEBUG can also be used as a very “” scripted debug interpreter using the above syntax.
