4. When the formatting is finished, the HP 50g displays the message
"FORMAT FINISHED. PRESS ANY KEY TO EXIT". To exit the system

The SD card is now ready for use. It will have been formatted in FAT32
format.
Accessing objects on an SD card
Accessing an object on the SD card is similar to when an object is located
in ports 0, 1, or 2. However, port 3 will not appear in the menu when you
are using the LIB function (
‚á). The SD files can only be managed
using the Filer, or File Manager (
„¡). When starting the Filer, the
Tree view will show:
Long names of files on an SD card are supported, but are displayed in 8.3
format in the Filer (that is, their names are truncated to 8 characters and a
three character extension is added as a suffix). The type of each object
will be displayed, unless it is a PC object or an object of unknown type. (In
these cases, its type is listed as String.)
In addition to using File Manager operations, you can use STO and RCL to
store objects on, and recall objects from, the SD card.
Storing objects on the SD card
To store an object, use function STO as follows:
• In algebraic mode:
Enter object, press K, type the name of the stored object using port 3
(e.g., :3:VAR1), press `.
• In RPN mode:
Enter object, type the name of the stored object using port 3 (e.g.,
:3:VAR1), press K.
