Hi, I need to know how I can get certain AmigaDOS calls (CreatDir, CurrentDir, DeleteFile, Lock, Open, etc.) to acutally go to various routines that I would write. This "feature" needs to be turned on and off at will. Any help would be most appreciated. -- +----------------------------------------------------------------------------+ | // Only /\ kxs5829@ultb.isc.rit.edu | |\\ // /--\MIGA kyle@ritcsh.cs.rit.edu | | \X/ Rochester Institute of Technology |

You would need to directly mangle the global vector, which requires High Wizardry, and is specifically not supported in 1.4 because its format is going to be changed. In particular, SetFunction() will not work for this purpose. It sure would be handy to be able to do this, though, wouldn't it? I don't know for sure whether hacking the global vector would work 100% or not; I've been meaning to try it one of these days. The main question in my mind is whether the system itself always uses the global vector, or whether it is sometimes bypassed internally, which would make even this un-Zen hack unreliable. The subject of "ROM-tags" comes to mind, but I don't recall any details, nor where to look for them.
