Help Reading Files into Fortran

[frying_pan_cat]

Hi,

I have some data files that I am trying to read into Fortran but I can't seem to get it to work. I have the data both as text and binary files but neither seems to work.
My code is

	PROGRAM EQLAT
	
	IMPLICIT NONE	
	
	REAL	::	realvalue ;
	CHARACTER(len=21)	::	FILENAME ;
	INTEGER	::	i ;
	
	FILENAME='ggap1979021700pvw.txt' ;
	
	! Open and read the file
	OPEN(UNIT=8,FILE=FILENAME,FORM='UNFORMATTED'
     &		,STATUS='OLD') ;
	
	i = 1 ;
	DO
		READ (8,END=999,ERR=1000) realvalue ;
		WRITE (*, '(I5, ": ", 1PE13.6)') realvalue ;
		i = i + 1 ;
	ENDDO
	
999	WRITE (*, '(/"End-of-file when i = ",I5)') i ;
	STOP
	
1000	WRITE (*, '(/"ERROR reading when i = ", I5)') i ;
	STOP
	
	END PROGRAM EQLAT

and in the text file the data appears in the form

35718 1
1.71675e-06
1.29579e-06
9.00909e-07
6.40139e-07
5.06028e-07
4.68775e-07
5.24655e-07

where the first line isn't important.

When I try to read the files I either get the error message or the end of file message without any output

If anyone could help me to get this working I would be very greatful

Thanks
