C----------------------------------------------------------------------
subroutine ftgpve(iunit,group,felem,nelem,nulval,
& array,anynul,status)
C Read an array of r*4 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 r the value to be assigned to undefined pixels
C array r 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 written by Wm Pence, HEASARC/GSFC, June 1991
integer iunit,group,felem,nelem,status,row
real nulval,array(*)
logical anynul,flgval
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)
call ftgcle(iunit,2,row,felem,nelem,1,1,nulval,
