Help for COPY

Copy is a simple program which can be used to copy all or
part of an image to another file.  The size and bands fields
are used to determine a window into the input file.

Copy works both on labeled and unlabeled images, although for
an unlabeled image it is usually best to specify INSIZE,
FORMAT, and ORG to ensure that the proper size image is read.

To write an unblocked tape file, the NOBLOCK keyword may be given.

The maximum record size that may be copied is 200,000 bytes.
