x86 Assembler - Debugger

This app is a low-level programming and debugger tool for MS-DOS executables.

An assembly (or assembler) language, often abbreviated asm, is any low-level programming language, in which there is a very strong (but often not one-to-one) correspondence between the assembly program statements and the architecture's machine code instructions.

The debugger feature has convenient single-step and conditional breakpoint facilities. The assembly can be written directly through this application.

In case of preference, an assembly can be written with the aid of an internal editor. It can be compiled with the built-in assemblers (MASM, TASM) and can be debugged with the debugger application. For such use, the must be familiar with the MSDOS environment.
