program rad_dy_read
c
c This program reads anonymous FTP ascii format daily radiation files,
c   for example 0n156e_dy.rad. It creates real time series arrays
c   which are evenly spaced in time.
c
c   Also created is an integer array of quality
c
c You can easily adapt this program to your needs.

c
      open(1,file=infile,status='old',form='formatted')
c 
c Read total number of hours and blocks of data.
c
      read(1,10) nday, nblock
   10 format(63x,i6,7x,i3)
c
      write(*,*) nday, nblock
c
c Read the missing data flag
c
      read(1,20) flag
   20 format(20x,f6.1)
c
      write(*,*) flag
c
c  Initialize data arrays to flag and quality arrays to 5.
c
      do n = 1, nt
        rad(n) = flag
        iqrad(n) = 5
      enddo
c
c Read the data.
c
      do m = 1, nblock
        read(1,30) n1, n2, nn
        read(1,50) deprad
        read(1,'(a)') header

c Now write out the data and quality arrays to the standard output. 
c
      write(*,*) deprad
c
