A save file is used with save and restore commands to retain data that would otherwise be written on tape or diskette.
The file can also be used like a database file to read or write records that contain save/restore information. A save file can also be used to send objects to another user on the SNADS network.
You can use the Copy Object (CPY) command to copy a save file both to and from a stream file. However, when copying a stream file back into a save file object, the data must be valid save file data (it must have originated from a save file and been copied into a stream file).
By using a PC client, you can also access the save file and copy the data to your PC storage or LAN. Keep in mind, though, that data in save files cannot be accessed through the Network File System (NFS).
