I admit it. During the last few years of all the discussion/publication of AIF features I have been just paying half-attention. But now I might have a need for some features that might be available from an AIF type capability. Can someone help me understand how this works? At this time my questions are: 1. How does one know what AIF stuff is available? 2. Are AIF instrinsics on every HP system so I can distribute an application to a target system without worry? 3. Do I have to buy a developers kit to learn how to call these AIF routines? 4. Assuming 3 is yes, is it technically possible to call the AIF routines without having such a kit if you happened to know the calling parameters? Please enlighten me folks. A little knowledge is very dangerous and I would like to get less dangerous. TIA. -- Duane Percox (Quintessential School Systems) [log in to unmask]
