x86 assembly language for MS-DOS: Hello, world

I do a demonstration on how to get started programming in x86 assembly language for the MS-DOS operating system using NASM and DOSBox-X. We write a "hello, world" program, assemble and run it, and then disassemble and analyze the executable COM file. NASM: https://nasm.us/ DOSBox: https://www.dosbox.com/ DOSBox-X: https://dosbox-x.com/ Intel 8086 CPU user manual: https://edge.edx.org/c4x/BITSPilani/E...
