C----------------------------------------------------------------------
subroutine ftppni(ounit,group,felem,nelem,array,nulval,status)
C Write an array of i*2 values into the primary array.
C Data conversion and scaling will be performed if necessary
C (e.g, if the datatype of the FITS array is not the same as the
C array being written). Any input pixels equal to the value of NULVAL
C will be replaced by the appropriate null value in the output FITS file.
C ounit i Fortran output unit number
C group i number of the data group, if any
C felem i the first pixel to be written (this routine treats
C the primary array a large one dimensional array of
C values, regardless of the actual dimensionality).
C nelem i number of data elements to be written
C array i*2 the array of values to be written
C nulval i*2 pixel value used to represent an undefine pixel
C status i returned error stataus

integer ounit,group,felem,nelem,status,row
integer*2 array(*),nulval
C the primary array is represented as a binary table:
C each group of the primary array is a row in the table,
C where the first column contains the group parameters
C and the second column contains the image itself
row=max(group,1)
