REPL for Assembly

[madanra]

Does anyone know of a REPL for Assembly? (Specifically x86 assembly)

I guess such a REPL would have a register window, probably a memory window, displaying something like what Bochs outputs from the 'r' and 'xp' commands in its debugger, along with a way of entering assembly commands.

The old MSDOS debug program could assemble, disassemble, do pretty much anything to the machine.

I know of one or two for real/v86 mode in a DOS environment. I don't know of anything that would be suitable for protected mode OS development or for developing userspace programs for modern OS's.
