&FSTAT
Allows access to the status field of the file header. The status field contains a user-definable integer which can be used for recording the status (e.g., revision number) of the file.
NOTE: You must open the appropriate directory and/or file header
before you execute this GPA using the FHREAD statement. If you want to access
more than one file or directory, you can use the DOPEN and DNEXT statements to
cycle through the files.
NOTE: This GPA works only on part files.
