--This file is the authoritative definition of File Types for Pilot files for Client purposes. In this module are defined the types peculiar to Pilot’s own files as well as the ranges of the types defined by all clients, applications, and supporting software. Each such client, application, and supporting software project should maintain its own file of File Types for its own subrange.

--Style Note: The subranges for the different applications, etc., are declared as subrange types of CARDINAL. The constants are declared to be values of the type File.Type (the correct type to be passed to thee File.Create operation of Pilot). The value of each constant is constructed from the appropriate subrange type in order that range checking can be applied by the compiler (when this feature becomes available). This style is recommended for client maintained files of subranges of File Types.

FileType: TYPE = File.Type;

-- These are copied from PilotFIleTypes.mesa; nobody should be using them

PilotFileType:TYPE = CARDINAL[0..256);
