Years ago, when I first heard of example code making use of the variables Foo and Bar, there were four others, sort of a standard sequence:
foo bar baz eek moof gleep
Nowadays, the only place I can find reference to them is in help files for a multiplayer text game engine called ‘PennMUSH’
This link (a href="http://www.faqs.org/rfcs/rfc3092.html)"http://www.faqs.org/rfcs/rfc3092.html)/a refers to a different sequence:
Foo: First on the standard list of metasyntactic variables used in syntax examples (bar, baz, qux, quux, corge, grault, garply, waldo, fred, plugh, xyzzy, thud).
Plugging my new magic catchphrase ‘metasyntactic variables’ into Wikipedia then sends me off on a long, merry chase into programming nostalgia I don’t think will allow me to get any actual work done today… Among other things, uncovers additional variables without clearly indicating their position in sequence:
bat, shme, spam, eggs, needle, haystack beekeeper, blah, blarg,dothestuff, grault, hoge, kalaa, mum, puppu, sub, temp, test, var, momo
I know I have a lot of free time on my hands, but the author of that Wikipedia article…
