VOLFILE
Specifies the full path and file name of the input header (volume) file.
IMGFILE
Specifies the full path and file name of the file that contains the image data to be read.
MTCH
MTCH is an output parameter. Upon completion, CDSH writes the three values reported from the input image on the CD to this parameter.
These values can be used by automated CD-reading procedures.
REPORT
Specifies where to direct the generated report.
Available options are:
MONITOR
The program progress can be monitored by printing the percentage of processing completed. A system parameter, MONITOR, controls this activity.
Available options are:

CDSH reads an LGSOWG source header from CD and prints out a report. Only the LGSOWG CD format is supported.
You must specify the full path and file names for the volume descriptor (header file) and the image data.
The MTCH output parameter contains the number of pixels, lines, and channels read from the CD.
