calling a plpgsql procedure

Sorry to post such a stupid question.  I have read the "create
function" documentation and searched old mailing lists, but I can't
seem to find an example of how to call a plpgsql procedure that isn't
associated with a trigger.

In Oracle (old platform) I used:

begin update_cur_res('VALUE-HERE'); end

This doesn't work in postgres as far as I can tell.  I've tried some
other things as well and failed, such as

psql $mydb
> update_cur_res('VALUE-HERE');

which gives a message that I have a syntax error near the semi-colon.
Help?

Thanks,

P.S. Why does the "search documentation" option on the web page only
accept 15 characters?
