Some information: 1. The driver is now available - DEC part number YT-GS001-01, cost $275.00 . The software has been in use for 18 months; however it is distributed 'unsupported' . An improved ISO-9660 driver will be available as part of a new release of VMS 'later in the year'. 2. The current driver supports only ISO-9660 level one implementation - restricted to 8 + 3 character (12 byte) file names. The VMS release will support the full standard (level 2 or 3?) which allows 31 byte file names. A known bug with the current software is that you can't have a subdirectory with the same name as its root'ed directory (example: [mydir.mydir]foo_bar.txt will not work). The driver doesn't support the proposed Rockridge ISO-9660 extensions - Larry said these are 'very preliminary'. For those contemplating producing a CD-ROM with a file structure that can't conform to the current ISO-9660 standard (examples: file names too long), an alternative is to pre-master in FILES11 format. FILES11 is a native VMS file system that will be usable on VAX's but not on platforms using a different OS. Mike Chalup Data Banks Group IntelliGenetics, Inc.
