Repoting tools and stored procedures?

HI All, I am trying to develop some reports using a windows base report writer and using stored proc's as the data source for a report. I am yet to find a report writer that supports stored procedures on Informix. Is anyone else using stored procedures to produce reports on the windows platform(16 or 32)? If so then I would be interested to hear what reporting tool and connectivity you are using. Thanks in advance for your help Jason Hay
