I am using vms after too many years. IN particular I have qio calls to deal with. Can some one explain the difference between IO_READ*BLK where the block is physical, logical or virtual. The documentation I have available to me distinguishes the calls but thats it. Why would I use one rather than the other?? Jerry Freedman,Jr
