Additional Information
The tfprotect and tprotect macros were implemented to control change permissions on frames and tags respectively. For now, these are equivalent to the cmsetrights and cmtxtrights that used to be part of the ODBC extension. This extension is not available in the Unicode version, hence the need for some macros that work in all versions.
The macros are quite primitive as there are no dialog box equivalents. The permissions system is also quite basic in that it offers the lowest level of protection. For example, if a tag has modify protection set, it will not be possible to add or remove a password. It will also not be possible to add or remove the tflock property.
