Changing a field value to NULL

I know the trick of using ctrl-0 to change it individually, but is there a
syntax that I can use as in the UPDATE to change a BUNCH of fields at the
same time. When changing fields I usually use the
UPDATE <table>
SET <field> = <parameter>
WHERE <field> = <parameter>
How do I do this to set a field as null where the parameter is 'No
Response'?
TIA
JCNever mind. I figured out what I was doing wrong. Dumb mistake.
