My fellow Ada-Teamers, I am about to venture deeply into the world of streams. In particular, I want to extend the Root_stream_type. I haven't found much literature to help guide me. Can anyone with experience in this area respond with their expertise or point me to documentation/examples that I might use. Thanks...mike ------------------------------------------------------ Mike Kamrad [log in to unmask] BlazeNet http/ Suite 300 1.508.370.4343 x139 1671 Worcester Road 1.508.370.4344 FAX Framingham MA 01701 "Because 0000,0000,ffffIT should be Easy"
