Note that if the name of the object you intend to store on an SD card is longer
than eight characters, it will appear in 8.3 DOS format in port 3 in the Filer
once it is stored on the card.
Recalling an object from an SD card
To recall an object from the SD card onto the screen, use function RCL, as
follows:
Θ In algebraic mode:
Press „©, type the name of the stored object using port 3 (e.g.,
:3:V R1), press `.
Θ In RPN mode:
Type the name of the stored object using port 3 (e.g., :3:V R1), press
„©.
With the RCL command, it is possible to recall variables by specifying a path in
the command, e.g., in RPN mode: :3: {path} ` RCL. The path, like in
a DOS drive, is a series of directory names that together specify the position of
the variable within a directory tree. However, some variables stored within a
backup object cannot be recalled by specifying a path. In this case, the full
backup object (e.g., a directory) will have to be recalled, and the individual
variables then accessed in the screen.
Note that in the case of objects with long files names, you can specify the full
name of the object, or its truncated 8.3 name, when issuing an RCL command.
Evaluating an object on an SD card
To evaluate an object on an SD card, insert the card and then:
1. Press . This puts a double colon on the edit line with the cursor
blinking between the colons. This is the way the HP 50g addresses items
stored in its various ports. Port 3 is the SD card port.
2. Press 3™³~~ [name of the object] `. This will place the
name and path of the object to be evaluated on the stack.
3. To evaluate the object, press μ.
