Trigger Procedures

Is there a way of passing NEW. fields into a trigger procedure - I know
that they are automatically available - but there is a reason...

We 'build' the trigger procedures when we define the table - typically
we have a common 'trace' procedure that gets fired on update/insert.
This function takes a series of arguments - one of which is a variably
named foreign key.
ie the trace_action could be called as:
CREATE TRIGGER insert_sourcedetprodTrace BEFORE INSERT ON sourcedetprod
FOR EACH ROW
EXECUTE PROCEDURE trace_actions (
'insert',
'sourcedet',
'sourcedetprod',
'Products Added',
NEW.sourcedetRecNo,
NEW.recNo
);
OR it could be called as:
CREATE TRIGGER insert_sourcedetupgrTrace BEFORE INSERT ON sourcedetupgr
FOR EACH ROW
EXECUTE PROCEDURE trace_actions (
'insert',
'sourcedetprod',
'sourcedetupgr',
'Upgrade Items Added',
NEW.sourcedetprodRecNo,
NEW.recNo
);

At the moment, I can't seem to pass the NEW values into trace_actions.
Similarly, as trace_actions is a common process, I have no way of
knowing whether NEW contains 'sourceDetRecNo' or 'sourceDetProdRecNo'
(unless I case the table name)

I know I can get around this by splitting the common trace_actions into
table specific traces, but I'm hoping that there's something that I've
missed and I can use some form of syntax like above.......
