Use the COPY command to indicate the number of copies that the file represents. This is most applicable to print or program output.
The COPY statement must come after a FILE command and should preceed any DATA commands.

The syntax is

COPY     COPIES

copies

where

copies

is the number of copies to be printed, displayed, submitted, punched, or otherwise processed

This attribute is generally most useful for print jobs, though it can be used for other media types.
