Google Unveils Code Search
derek_farn writes, "Google now has a page that supports source code searching. I hope they extend it to be more programming-language aware (e.g., search for identifiers and functions) like the specialist code search sites (Krugle, Koders, and Codease), who probably now have very worried investors. I don't see any option to search for Cobol. I guess there is not a lot of Cobol source available on the Internet, even although there is supposed to be more Cobol source in existence than any other language (perhaps that statement is not true in the noughties)." From the Cnet.com article: "Google engineers, many of whom participate in open-source projects, already use these code searching capabilities internally. Since it is a Google Labs project, the company is not yet seeking to monetize searches through ads."
not to undermine the Google's work but in the meantime you may as well try this one

Google is not the first to unveil a code search service. Previously, Famous book publisher O'Reilly launched a beta of its Code Search service last month that allows users to search a combined 2.6 million lines of code published in its books.
...just look at this :

Total lines of code evar champion: VB.
It passed "legacy language" COBOL back in the 90's.
