Fortran runtime error: Cannot read from file opened for WRITE

Hi Friends,
What is the problem in my statements?

!6. Model I/O file properties
!6.1 Input
!---open boundary conditions (2-D)
modfiles(io_2uvobc,1:2,1)%status = 'N'
modfiles(io_2uvobc,2,1)%form = 'A'
modfiles(io_2uvobc,2,1)%filename = 'DATA/discharge.csv'
modfiles(io_2uvobc,2,1)%tlims = (/0,int_undef,1440/)

!6.2 output

! ---open boundary conditions (2-D)
modfiles(io_2uvobc,1:2,2)%status = 'W'
modfiles(io_2uvobc,1:2,2)%form = 'U'

!1. Open file

IF (modfiles(io_2uvobc,ifil,1)%iostat.EQ.0) THEN
CALL open_filepars(modfiles(io_2uvobc,ifil,1))

iunit = modfiles(io_2uvobc,ifil,1)%iunit
modfiles(io_2uvobc,ifil,1)%iostat = 1
READ (iunit,*)
GOTO 1000

ciodatetime = CStartDateTime

!2. Read data
READ(iunit,*) qdis1,qdis2

!---close file
CALL close_filepars(modfiles(io_2uvobc,ifil,1))

I try to add a river discharge file to my program but when I run it, this error comes up:
Fortran runtime error: Cannot read from file opened for WRITE

Thank you,

It is a long time since I looked at Fortran and you don't specify the compiler. Do you need to open READWRITE?

seeing as code tags were not used

my first guess is the formatting and tabs

this is the rest of the code that I didn't put in my first post:

1000 CALL log_timer_out()

my compiler is gfortran and the compiling is fine apparently.

John, could you please explain more?
Thanks from both of you,
