$!_TITLE CDCOPY - Command file to copy CDROM files to magnetic disk
$!
$!_DESCR
$!
$!     The CDCOPY command file is to be used by VAX/VMS systems for
$!     copying data files from CDROM media to VMS magnetic disk media.
$!     This command file is used  in conjunction with the VFS-ISO 9660
$!     MOUNT field test kit which allows VMS interface with the CDROM
$!     ISO volume and directory standard.
$!
$!     The current VMS interface to CDROMs (VFS field test kit) has
$!     problems with files that have extended attribute records with
$!     a print control value of 0. The dcl COPY command, and other
$!     DCL commands, generates an error message when trying to access
$!     these kinds of files. The dcl CONVERT utility will properly
$!     copy these files to the VMS environment. The CDCOPY command
$!     file will create an appropriate FDL file for the given input
$!     CDROM file and then execute the CONVERT utility.
$!
$!     The CDCOPY command file will convert fixed-length,
$!     variable-length, and stream record files. If a file on the
$!     CDROM does not contain an extended attribute record, then the
$!     command file assumes the file is a stream record file and
$!     convert it accordingly.
$!
$!     BUG NOTE: Stream record files are not properly converted to the
$!     VMS format. The convert utility program adds a carriage-return
$!     line-feed sequence on every 512 byte boundary in the file. These
$!     extraneous bytes can be removed by editing the converted
$!     document.
$!
$!     HOW TO RUN THE COMMAND FILE:
$!
$!     You can run the CDCOPY command file with the following command:
$!
$!     $@CDCOPY  in-spec out-spec
$!
$!     where 'in-spec' is the input file specification and 'out-spec'
$!     is the output file specification. Wild card file specifications
$!     are permitted.  Shown below are a few examples of how to run
$!     the command file (the CDROM device name is assumed to be DUD7:):
$!
$!     $@CDCOPY DUD7:[INDEX]IMGINDEX.TAB *
$!     $@CDCOPY DUD7:[MG05NXXX]*.IMG *
$!     $@CDCOPY DUD7:[GAZETTER]GAZETTER.TAB OUT:TEST.TAB
