If you wanted your program to be useful, you had to write it entirely in Assembly Language. This takes us back to the days when C compilers weren’t as good at optimizing code as they are today, processors weren’t nearly as fast and memory was at a far greater premium. Microsoft posted the source code to MS-DOS versions 1 and 2 a few years ago, which again is also entirely written in 8086 Assembly Language. Programming with 64-Bit ARM Assembly Languageīut long ago, my first job out of University involved some Intel 80186 Assembly Language programming, so I was interested when Microsoft recently posted the source code to GW-Basic which is entirely written in 8086 Assembly Language.Raspberry Pi Assembly Language Programming.These days I mostly play around with ARM Assembly Language and have written two books on it:
