RESTORE(: Port_Number : Backup_Name)
For example, to restore the HOME directory out of backup object HOME1,
use:
RESTORE(:1:HOME1)
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: PURGE(: Port_Number : Backup_Name)
In RPN mode, use: : Port_Number : Backup_Name PURGE
To restore a backup object:
• Use the File Manager („¡) to copy the backup object from Port
memory to the HOME directory.
