TechWhirl (TECHWR-L) is a resource for technical writing and technical communications professionals of all experience levels and in all industries to share their experiences and acquire information.
For two decades, technical communicators have turned to TechWhirl to ask and answer questions about the always-changing world of technical communications, such as tools, skills, career paths, methodologies, and emerging industries. The TechWhirl Archives and magazine, created for, by and about technical writers, offer a wealth of knowledge to everyone with an interest in any aspect of technical communications.
It seems that there is not a common convention. I've seen nearly all your
examples at one time or another. The most common one I've seen lately, in
the context of C, C++, and Java, is the "0x20" convention.
Whatever you do, pick one, use it everywhere, and explain it somewhere,
preferably in a few places where you've used it in the document.
