The line-oriented debugger DEBUG.EXE is an external command in operating systems such as DOS, OS/2 and Windows (only in 16-bit/32-bit versions [1]).. DEBUG can act as an assembler, disassembler, or hex dump program allowing users to interactively examine memory contents (in assembly language, hexadecimal or ASCII), make changes, and selectively execute COM, EXE and other file types.
The 80386 also introduced the two new segment registers FS and GS as well as the x86 control, debug and test registers. The new instructions introduced in the 80386 can broadly be subdivided into two classes: Pre-existing opcodes that needed new mnemonics for their 32-bit OperandSize variants (e.g. CWDE, LODSD)
SASM (short for SimpleASM) is a free and open source cross-platform integrated development environment for the NASM, MASM, GAS and FASM assembly languages. It features syntax highlighting and includes a debugger. [1] SASM is intended to allow users to easily develop and run programs written in assembly language.
In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions.

The debug registers allow programmers to selectively enable various debug conditions associated with a set of four debug addresses. Two of these registers are used to control debug features. These registers are accessed by variants of the MOV instruction. A debug register may be either the source operand or destination operand.
The GNU Debugger (GDB) is a portable debugger that runs on many Unix-like systems and works for many programming languages, including Ada, Assembly, C, C++, D, Fortran, Haskell, Go, Objective-C, OpenCL C, Modula-2, Pascal, Rust, [2] and partially others.
Turbo Debugger — Pascal/C/assembly debugger for DOS; Undo LiveRecorder — C, C++, Go, Rust, Java time travel debugger; Ups — C, Fortran source level debugger; Valgrind — Valgrind is a programming tool for memory debugging, memory leak detection, and profiling. VB Watch — debugger for Visual Basic 6.0
Winpdb debugging itself. A debugger is a computer program used to test and debug other programs (the "target" programs). Common features of debuggers include the ability to run or halt the target program using breakpoints, step through code line by line, and display or modify the contents of memory, CPU registers, and stack frames.
