field substitution

I have a PL/SQL field name in a variable FNAME i.e. Fname := 'Eventno'

How can I reference the old value of that field name programatically.

i.e. old.fname should return the same result as old.eventno

Is there a macro substitution character such as old.&fname that will make the expression work?
