I'd suggest, Python, Perl, TCL, Ruby, ... anything but csh (or bash) for
a job like this.

I know Python has BDB support:

I'm sure all the other languages you might want to use will have support
for BDB, or sqlite.

Although reading and writing a 60K csv file probably isn't that big a
deal, unless you're doing it quite often.  In Python you could import a
CSV file into a dictionary, which makes lookup very fast.
