+C       Read an array of i*2 values from 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
+C       as the array being read).
+C       Undefined elements will be set equal to NULVAL, unless NULVAL=0
+C       in which case no checking for undefined values will be performed.
+C       ANYNUL is return with a value of .true. if any pixels were undefined.
+
+C       iunit   i  Fortran unit number
+C       group   i  number of the data group, if any
+C       felem   i  the first pixel to be read (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 read
+C       nulval  i*2  the value to be assigned to undefined pixels
+C       array   i*2  returned array of values that were read
+C       anynul  l  set to .true. if any returned elements were undefined
+C       status  i  returned error stataus

+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(1,group)
