I always have problems when NOTs are involved, so I do my best to avoid them.

As I read the expression it would be as follows:

std_hoursonly = 'N' .and. ! (dcpay.payevent = '99' .and. dcpay.paycode = '00')
      | true |     AND  NOT (             | true |  AND         | false | )
      | true |     AND  NOT ( false )
      | true |     AND  | true |

So I guess I'm not sure what you mean when you say "...and also when the second half of the expression is .f.!".

Does the above reflect what you mean by that, or do you mean something else?

good luck
