X-Midas Users Take Note:
The PROTECT and UNPROTECT functions in FILE are used in place of the X-Midas PROTECT and UNPROTECT commands.
The DETACH function in FILE is used in place of the X-Midas DETACH command (since NeXtMidas 2.9.1.)
The OPEN and CLOSE functions work similar to the X-Midas ENV FILE OPEN command.
