Hello Brian,

If your book is pure MASM, you might be interested in the free alternative 
NASM, or the Net-wide Assembler. It has very similar syntax to the MASM 
examples; of course anything Windows/DOS-Centric won't work but the 
examples themselves will if you adapt them. It is a VERY nice little 
assembler and a godsend for those of us that got our start on MASM and are 
familiar with MASM syntax.

NetBSD has a nice pkgsrc entry for nasm and it works pretty much "out of 
the box". For information about how to write your first hello-world, I've 
written some (possibly out of date) tutorials that are completely 
over-done. All I needed to do was link my normal code with crtbegin and 
crtend. :)

Here're the URLs, they're all NASM-specific:

Chapter 1: Introduction to Pain

Chapter 2: A Trip Through ELFen Hell
Subtitle: How I learned I went through way more pain than necessary

Good luck! Assembly can be vastly rewarding in a UNIX-style environment!
