C--------------------------------------------------------------------------
subroutine ftpthp(ounit,heap,status)
C Define the starting address for the heap for a binary table.
C The default address is NAXIS1 * NAXIS2. It is in units of
C bytes relative to the beginning of the regular binary table data.
C This subroutine also writes the appropriate THEAP keyword to the
C FITS header.
C ounit i Fortran I/O unit number
C heap i starting address of the heap
C OUTPUT PARAMETERS:
C status i returned error status (0=ok)
