Ah, the everpresent foobar/fubar question.
The Jargon File says:
It has been plausibly suggested that "foobar" spread among early computer engineers partly because of FUBAR and partly because "foo bar" parses in electronics techspeak as an inverted foo signal; if a digital signal is coded so that a positive voltage or high current condition represents a "1", then a horizontal bar is commonly placed over the signal label.
I.e. the generic variable "foobar" or "foo bar" is probably a derivative of "fubar", but they do not mean the same thing. "foo" and "bar" (or "baz" or "bat") are so-called metasyntactic variables, words that don't mean a thing by themselves but are used when a nonsensical variable is needed, for example "for [foo] to happen, [bar] must take place first". Or, another example:
chomp($foo=`which echo`);
system "$foo Hello World > bar";
The meaning lord of the mark used in

the answers to the French lit question are FOOBAR. Dumas, really |
is therefore not exactly precise, but I'm not going to call it incorrect.
What comes to "recognition vs. recovery", it's the same with "remember vs. recall" in IIRC - it doesn't matter.
