RESTORE(: Port_Number : Backup_Name)
For example, to restore the HOME directory out of backup object HOME1,
use:
In RPN mode use:
: Port_Number : Backup_Name ` RESTORE
Note: When you restore a HOME directory backup two things happen:
The backup directory overwrites the current HOME directory. Thus, any
data not backed up in the current HOME directory will be lost.
The calculator restarts. The contents of history or stack are lost.

Storing, deleting, and restoring backup objects

To create a backup object use one of the following approaches:
Use the File Manager („¡) to copy the object to port. Using this
approach, the backup object will have the same name as the original
object.
Use the STO command to copy the object to a port. For example, in
algebraic mode, to back up variable A into a backup object named AA
in port 1, use the keystroke sequence:
@@@A@@@ K „ê1™~a~a`
Use the ARCHIVE command to create a backup of the HOME directory
(see above).
To delete a backup object from a port:
Use the File Manager („¡) to delete the object as you would a
variable in the HOME directory (see Chapter 2 in the User's Guide).
Use the PURGE command as follows:
In algebraic mode, use:
In RPN mode, use:
To restore a backup object:
Use the File Manager („¡) to copy the backup object from Port
memory to the HOME directory.
RESTORE(:1:HOME1)
