User Permissions

Permission for certain operations can be granted and denied by the user. Any operation with insufficient permissions will throw ExcNotPermitted. Selecting View→Permissions opens a dialog to edit the permissions.

Each m function presented in the library document lists the permissions it requires, as described in the previous section.

The individual permissions are:

Name	Bit	Meaning
ReadDoc	1	Read access to files in system.docdir and its subdirectories.
WriteDoc	2	Write access to files in system.docdir and its subdirectories.
ReadApp	4	Read access to other application's data.
WriteApp	8	Write access to other application's data.
FreeComm	16	Access to free communication resources (receiving messages, Bluetooth).
ReadAll	32	Read access to all files.
WriteAll	64	Write access to all files. Granting write access to all files also allows modifying the permissions.
CostComm	128	Access to chargeable communication resources (sending messages, TCP/IP).
Device	256	Write Access to the device state (power, reboot).

Thus, if a function requires Read(file), then

• If file denotes a file or directory in system.docdir or one of its subdirectories, the ReadDoc permission must be granted for the function to succeed.
• If file denotes a file or directory outside system.docdir or one of its subdirectories, the ReadAll permission must be granted for the function to succeed.
