PL/PgSQL FOR syntax

    Hi,
What's the correct syntax to access rows in a FOR loop? I'm writing
a PL/PgSQL doc and seem to be making a mistake somewhere.I am referring to this:
[<<label>>]   FOR record | row IN select_clause LOOP       statements   END LOOP;
How do I access the rows within the for loop? row.field? 
Thanks,
-Roberto

Yes,
e.g.
declare
r record;
begin
for r in select statement loop r.fieldname can fetch the result from the select statment row by row
