Example 10 - Creating an A-Series and JOLIET hybrid CD Image
COPY COPYWRITE/LIBRARY TO #MYTESTVOLUME(CD,HOSTNAME=LOCAL, SCRATCHPOOL=ASERIESJOLIET);
 
Example10
 
  1. The ASERIESJOLIET intrinsic transform creates a hybrid CD which has 2 file systems. Each file is registered twice, once on each of the file systems.
  2. The A-Series partition is ISO9660, and the files have an Extended Attribute Record (XAR), and System Software can access the data using LogicalIO, KIND = CD.
  3. The JOLIET partition, translates the files to Windows format, that is, ASCII with variable length records terminated by a CR and LF.
  4. When the CD is mounted on a Windows system, it ignores the ISO9660 partition, and makes the JOLIET files available.
  5. When the CD is mounted on the A-Series it sees an ISO9660 Data CD, and ignores the JOLIET partition.
  6. This is a relatively slow process because the files are copied first to the cache, as they are deleivered by LIBRARY/MAINTENANCE, then reprocessed for the ISO9660 partition, and then reprocessed for the JOLIET partition.
