Example 21 - Copying a file from an ISO9660 partition of a CD Image file on disk
 
COPY COPYWRITE/LIBRARY AS "TEST.TXT" TO #MYTESTVOLUME(CD,HOSTNAME=LOCAL, SCRATCHPOOL=WINDOWSNT)[T];
IF (T(TASKVALUE)=0) THEN
BEGIN

T(STATUS=NEVERUSED);
COPY "TEST.TXT" FROM #MYTESTVOLUME(CD,LOCKEDFILE,HOSTNAME=LOCAL,SCRATCHPOOL=ISO9660)[T];

END;
 
 
  1. An ISO9660 CD image was created by copying a file using the WINDOWSNT intrinsic transform.
  2. Since COPYWRITE can copy a file from any of the file systems of a hybrid CD image, it must be told which file system the file resides on.
  3. The file could lie on the ISO9660 or JOLIET partition, or in the LIBRARY/MAINTENANCE partition.
  4. The LOCKEDFILE attribute told COPYWRITE that the CD volume was in an image file. The SCRATCHPOOL=ISO9660 told it that the file resides within the ISO9660 file system.
  5. The PDT utility function of COPYWRITE, or COPYWRITE for NT, can be used to find out what file systems exist on a CD or within a CD image file.
  6. If a file on an ISO9660 or JOLIET partition has no Extended Record Attribute (XAR), then it is copied as a FRAME STREAM file.
