I used DEBUG mostly to assemble rather than "debugging"... if that's your goal,

NASM is a good assembler with more similar syntax

Use gdb to then run the code, allow disassembly, and examine memory

gdb - the GNU project debugger is the Linux standard debugger. It is far more powerful than DEBUG (if by that you mean the old DOS tool) and you should really learn at least the basics of how to use it if you are programming on Linux.

GDB 么，直接layout asm，或者bochs 也行的，你说的全在里面，GDB很强大!

gdb很强大，应该包含类似windows里面 DEBUG 程序的功能，所以应该去学习如何使用 gdb
