Chapter 20. MASM vs. NASM vs. TASM vs. WASM

This chapter reminds me of the old Batman and Robin show where in a fight scene we see sound effect words flash on screen such as "OOF," "KABONG," "ZING," "MASM," "ZOT," "TASM," "ZANG," "WASM," and "POW." These, by an amazing coincidence, are the war cry of the assembly language programmer. Wars have started for far less than trying to get one of these programmers to use a different C/C++ compiler or assembler. At one company I spent almost two years writing a good portion of the application core libraries and all the documentation for their SDK that allowed internal and external programmers to write online computer games using dedicated game servers. For the last year and a half there I worked on their ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
