(2007-11-16) Missing definition __computing__ dictionary. It includes lots of terms from related fields such as mathematics and electronics, but if you're looking for (or want to submit) words from other subjects or general English words or other languages, try {(http://wikipedia.org/)}, {(http://onelook.com/)}, {(http://yourdictionary.com/)} or {(http://reference.allrefer.com/)}. If you've already searched the dictionary for a computing term and it's not here then please __don't tell me__. There are, and always will be, a great many missing terms, no dictionary is ever complete. I use my limited time to process the corrections and definitions people have submitted and to add the {most frequently requested missing terms (missing.html)}. Try one of the sources mentioned above or {(http://techweb.com/encyclopedia/)}, {(http://whatis.techtarget.com/)} or {(http://google.com/)}. See also the note on {bad cross-references (dangling.html)}. What does ... mean? How do I ...? Where can I find ...? I'm afraid I don't have time to answer personal requests for definitions, help configure your PC, do your homework, or explain what that Windoze error message means, etc. so please __don't ask me__. How do I submit a definition? I'm afraid I can't accept any more new definitions at the moment, I have a huge backlog awaiting processing.

Occurrences of $1 are replaced by the first {actual argument} provided by the user when the {shell script} is run. $2 is replaced by the second argument, and so on up to $9. You may have arrived at this entry by following a {URL} like "http://foldoc.org?$1", which is actually a {template} used to generate pointers to FOLDOC definitions by replacing "$1" with the term to be defined, e.g. in a {wiki} {interwiki map}.
