Really not there.  I've bugged John D. about this (and he's
thinking about it).

You can read a keyword with  fits_read_key

When I work w/ fits files in idl, I usually read data and header,
modify the header slightly (history or comment...) and write back.

What I resorted to in my contamarf script were some of the low-level
fits routines:

..
  () = system( sprintf("cp %s %s", arf_in, arf_out ) );
  () = system( sprintf("chmod u+w %s", arf_out ) );

  variable col, hs ;
  variable fp = fits_open_file( arf_out + "[SPECRESP]", "w" );

  () = _fits_get_colnum (fp, "SPECRESP", &col);
  () = _fits_write_col (fp, col, 1, 1, arf );
  hs = sprintf ("contamarf: tstart = %f", tstart);
  () = _fits_write_history (fp, hs);
  hs = sprintf ("contamarf: contam file = %s", Acis_Contamination_File);
  () = _fits_write_history (fp, hs);

  fp = 0;


but the _fits_ ones are undocumented, and should be supplanted with
fits_ when they are done.

If it's convenient, you could probably import varmm.
