HP 48GX Hidden Directory

[DavidM]

Using the system's hidden directory to store objects would require all programs that access them to "jump through hoops" any time the objects need to be recalled or stored. You may want to consider the use of a "var hider" instead, which would probably be easier to use (and safer) for something like you are describing. Hidden objects in the HOME directory are universally available to all programs.

One such utility can be found here. Several others can be seen by querying the same site with "var hider".
