How to program an exception report, example of ALTERNATE IMAGE NUMBER

On an exceptions report, I only want to print records with problems. How do I tell it to skip (not print) the good ones? Do I do this in Pre-Display?

Start your OUTPUT Frame's "Select Image" ILF series with:

SET --- ALTERNATE IMAGE NUMBER = 0

Put the ILF that tests for exceptions below that. If a Record (or set of conditions in a Range-End frame) qualifies as an exception:

SET --- ALTERNATE IMAGE NUMBER = 1

You can also issue MESSAGE, WARNING, ERROR, or CANCEL ILF commands at this point. Paint whatever fields and text you'd like on the OUTPUT Frame's Image, and you have a customized exception report!
