While you are correct here, it's not a useful definition (except to internals types). My point is that RMS is sufficiently pervasive under VMS that the normal user or applications programmer has no need to make that distinction; RMS _is_ the interface to the file system. Providing a usable interface to the file system is a "joint effort" between the XQP (&| ACPs) and the higher level RMS calls. Talking to the XQP directly means block I/O only; a good foundation to layer a higher level system on top of, but not one that's particularly conducive to applications development. These things _are_ supposed to run applications, aren't they? 8-) -- Don Stokes, ZL2TNM (DS555) don@zl2tnm.gen.nz (home) Network Manager, Computing Services Centre don@vuw.ac.nz (work) Victoria University of Wellington, New Zealand +64-4-495-5052
