SQL Update Question

I need to write a DB fix, and rather than use RPG I wanted to use SQL.
One file, CLTMAS needs to be updated with a value on another file
AGTMAS.

The following SQL Select works and shows me all the values that I need
to work with:

SELECT a.kedagc, b.kedaga, b.kedbca FROM cltmas a, agtmas b WHERE
a.kedagc <> ' ' and a.kedagc = b.kedbca    

a.kedagc                        b.kedaga
b.kedbca

I need to set a.kedagc = b.kedaga when there is a join on the two
records. I tried using this as the basis of an UPDATE statement, but
can't get it working. I think I need a sub-select but can't work it out.
In rough terms I need to SET a.kedagc= b.kedaga using the above WHERE
clause.

Anyone got a spare two minutes?

Thanks.
