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.
It is used to analyze 64-bit executable files, while its counterpart, x32dbg, is used to analyze 32-bit executable files. Debugging is a process of looking into executable files translated into low-level assembly code, allowing the user of the debugger to see what is going on inside of an application; even if it is not open source.
This is a list of the instructions in the instruction set of the Common Intermediate Language bytecode. Opcode abbreviated from operation code is the portion of a machine language instruction that specifies the operation to be performed. Base instructions form a Turing-complete instruction set.
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
The first of these, the Basic Assembly Language (BAL), is an extremely restricted assembly language, introduced in 1964 and used on 360 systems with only 8 KB of main memory, and only a card reader, a card punch, and a printer for input/output, as part of IBM Basic Programming Support (BPS/360).
The Interactive Disassembler (IDA) is a disassembler for computer software which generates assembly language source code from machine-executable code. It supports a variety of executable formats for different processors and operating systems. It can also be used as a debugger for Windows PE, Mac OS X Mach-O, and Linux ELF executables.
Modifies stack for entry to procedure for high level language. Takes two operands: the amount of storage to be allocated on the stack and the nesting level of the procedure. INSB/INSW: 6C Input from port to string. May be used with a REP prefix to repeat the instruction CX times. equivalent to:
