currently defined in the HOME directory. You can also restore the contents of
your HOME directory from a back up object previously stored in port memory.
The instructions for these operations follow.
Backing up the HOME directory
To back up the current HOME directory using algebraic mode, enter the
command:
ARCHIVE(:Port_Number: Backup_Name)
Here, the only possible value for Port_Number is 0, and Backup_Name is the
name of the backup object that will store the contents of HOME. The : :
container is entered by using the keystroke sequence
„ê. For example,
to back up HOME into HOME1 in Port 0, use:
To back up the HOME directory in RPN mode, use the command:
: Port_Number : Backup_Name ` ARCHIVE
Restoring the HOME directory
To restore the home directory in algebraic mode use the command:
RESTORE(: Port_Number : Backup_Name)
For example, to restore the HOME directory out of backup object HOME1,
use:
RESTORE(:0: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.
