We are doing a convertion program and one of the fields we are converting is going from a Interger to a Logical or Bit. IIF() can not be done nicely for this. You could just replace using a true/false expression-
replace mylogicalfield with (myoldval=1) all
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
