CD2PICS - Convert PDS CDROM compressed and uncompressed image to PICS
PROGRAMMER:EELIASON

CD2PICS - Reads a PDS image on a CDROM and converts it to PICS format.

CD2PICS handles VOYAGER and VIKING images stored on CDROM. A new feature
has been recently added to read PDS image files with detached labels.
This new feature currently has been tested only on the PRE-MAGELLAN
CDROM disk. If a PDS detached LABEL/IMAGE files are  to be read, provide
the name of the label file (*.LBL) in the FROM= parameter.

CD2PICS was developed to handle VOYAGER and VIKING images stored on
CDROMs in the PDS image file format.  The program can convert both
compressed and uncompressed PDS image files which conform to version 1.0
of PDS' Object Descriptor Language (ODL). The original VOYAGER Space
Science Sampler disc (March 25, 1987) and the PDS interactive Data
Interchange Space Science Sampler disc of the same date can not be
accessed by this program.  You will need to continue to use the original
CDIN program for accessing this data.

Before CD2PICS can be run, you must first ALLOCATE and MOUNT the
CDROM reader.  Issue the following comands when reading an image
from the CDROM.

        TAE>ALL dub0:
        TAE>MOUNT dub0:/FOR
        TAE>CD2PICS FROM=dub0:[dir]image.ext TO=pics_file

        dub0: = device name of CDROM player. If your CDROM player
        device is not named DUB0: then replace dub0: with the correct
        name.

        [dir] = directory containing your file

        image.ext = name of file, be sure that the file name extension
        is included in the file name.
