EOF

 EOF (integer)

 Class:  Inquiry function - Generic

 Checks whether a file is at or beyond the end-of-file record.

 The argument represents a unit specifier corresponding to an open
 file.  It cannot be zero unless you have reconnected unit zero to a
 unit other than the screen or keyboard.

 The value of the result is .TRUE.  if the file connected to A is at
 or beyond the end-of-file record; otherwise, .FALSE..

 This function cannot be passed as an actual argument.

 Examples:

 Consider the following:

 !  Creates a file of random numbers, reads them back
       REAL x, total
       INTEGER count
       OPEN (1, FILE = 'TEST.DAT')
       DO I = 1, 20
         CALL RANDOM_NUMBER(x)
         WRITE (1, '(F6.3)') x * 100.0
       END DO 
       CLOSE(1)
       OPEN (1, FILE = 'TEST.DAT')
       DO WHILE (.NOT. EOF(1))
         count = count + 1
         READ (1, *) value
         total = total + value
       END DO
 100   IF ( count .GT. 0) THEN
         WRITE (*,*) 'Average is: ', total / count
       ELSE
         WRITE (*,*) 'Input file is empty '
       END IF
        STOP
       END
