<a href="../M/metasyntactic-variable.html"><i class="glossterm">metasyntactic variable</i></a>; see <a href="foo.html"><i class="glossterm">foo</i></a> for etymology.

Probably originally propagated through DECsystem manuals by Digital
|
||
Equipment Corporation (<a href="../D/DEC.html"><i class="glossterm">DEC</i></a>) in 1960s and early
|
||
1970s; confirmed sightings there go back to 1972. Hackers do
|
||
<span class="emphasis"><em>not</em></span> generally use this to mean
|
||
<a href="FUBAR.html"><i class="glossterm">FUBAR</i></a> in either the slang or jargon sense. See also
|
||
<a href="Fred-Foobar.html"><i class="glossterm">Fred Foobar</i></a>. In RFC1639, “<span class="quote">FOOBAR</span>” was
|
||
made an abbreviation for “<span class="quote">FTP Operation Over Big Address
|
||
Records</span>”, but this was an obvious <a href="../B/backronym.html"><i class="glossterm">backronym</i></a>.
|
||
It has been plausibly suggested that “<span class="quote">foobar</span>” spread among
|
||
early computer engineers partly because of FUBAR and partly because
|
||
“<span class="quote">foo bar</span>” parses in electronics techspeak as an inverted foo
|
||
signal; if a digital signal is active low (so a negative or zero-voltage
|
||
condition represents a "1") then a horizontal bar is commonly placed over
|
||
the signal label.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="foo.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../F.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="fool.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">foo </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> fool</td></tr></table></div></body></html>
