CLEO Help Notes: The Copy application file set command will copy all records associated with a specified application file set from one library to another. Since the same file may appear in many file sets, a parameter is provided to control whether the associated file, format, and field descriptions are also copied. Both the "from" and "to" libraries must be EXTOL system files libraries. This command is useful for copying file set information from (for example) test to production libraries on the same system. To save application file set records or to send them to another system, see the SAVFS and SNDFS commands.
