Backing up objects in port memory
The operation of backing up an object from user memory into one of the
memory ports is similar to the operation of copying a variable from one sub-
directory to another (see details in Chapter 2 of the User’s Guide). You can,
for example, use the File Manager (
„¡) to copy and delete backup
objects as you would do with normal calculator objects. In addition, there are
specific commands for manipulating back up objects, as described next.
Backing up and restoring HOME
You can back up the contents of the current HOME directory in a single back
up object. This object will contain all variables, key assignments, and alarms
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, Port_Number is 0, 1, 2 (or 3, if an SD memory card is available -- see
below), 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 1,
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:
