I would prefer not to use the UDF approach as it may not be available when user runs this or that report. I will keep trying the variations of IIF to see how I can get it to work.

The problem is definitely with the IIF() and probably the way SFReports views it. I changed my IIF() expression to
IIF( DATE_FLD1 > DATE_FLD2, 1, 0 ) and I still see bunch of asterisks.
