The Preferences extension is a Satellite Forms plugin that provides PalmOS Preference database Read Write functions.

This extension is used to read and write data from the PalmOS Preference area. The preference area can be thought of in the same way as a Windows Registry. For programmers that are neither familiar with PalmOS Preferences nor Windows Registry - the Preference area is a place where information about your program can be stored semi-permanently.

Features Include:

Data stored in the Preference area will remain even if:

• Program is exited
• Palm turned off
• Palm is Soft Reset (reset button)
• Palm is Hard Reset (Lost all power - BUT only if the palm has hotsynced since the data was placed into the preferences)

The preference area is the perfect location to store:

• The current form when the program is exited.
• Table positions when program is exited.
• Global variables which retain their value if the program is exited.
• Security Information that you wish to keep on the palm remains even if the application is removed or the palm wiped.
• Program attributes such as version number
• Settings (serial communication, modem or barcode scanner) that will remain even if the application is deleted or a new version is installed.
• Simple security functions to stop people copying your program.
• etc.
