             _fits_bad_keyword(c)  
 
     Returns error message due to invalid FITS keyword.  C is an array of  
     characters that compose the bad FITS keyword.  
interpreted function, defined at i/fits.i   line 2602  

             _fits_bintable_header(fh, nbytes, nrows, tfields)  
 
     Set/update header  information in  FITS handle FH  for a  binary table  
     extension.  NBYTES is the number of  bytes per row of the table, NROWS  
     is  the number  of table  rows  and TFIELDS  is the  number of  fields  
     (columns in  the table).  FITS  card "XTENSION" with  value "BINTABLE"  
     must already exists  in the header (this is  not checked).  FITS cards  
     "BITPIX",  "NAXIS",   "NAXIS1",  "NAXIS2",  "PCOUNT",   "GCOUNT",  and  
     "TFIELDS" get created/updated by this routine.  The value of PCOUNT is  
     computed by the routine and returned to the caller.

             _fits_digitize   - char -> number conversion array;  
             _fits_multiplier - multiplier;  
             _fits_alphabet   - allowed characters in FITS keys;  
             _fits_max_id     - maximum possible ID value.  
 
     Private  arrays  used  to   convert  FITS  keyword  to/from  numerical  
     identifiers.  If you experiment  a strange behaviour of FITS routines,  
     it may  be because one  of these arrays  get corrupted; in  that case,  
     just  run subroutine fits_init  to reinitialize  things (you  may also  
     have to rehash your FITS handles: see fits_rehash).

             _fits_format_comment(key)  
 
       -or- _fits_format_comment(key, text)  
     Private routine  to format  FITS commentary card,  return an  array of  
     80-character string(s).   Text comment, if longer  than 72 characters,  
     will result in more than one comment cards.

             _fits_format_complex(key, value)  
 
       -or- _fits_format_complex(key, value, comment)  
     Private routine to format FITS complex card, return a 80-character  
     string.  
interpreted function, defined at i/fits.i   line 1370  

             _fits_format_integer(key, value)  
 
       -or- _fits_format_integer(key, value, comment)  
     Private routine to format FITS integer card, return a 80-character  
     string.  
interpreted function, defined at i/fits.i   line 1340  

             _fits_format_logical(key, value)  
 
       -or- _fits_format_logical(key, value, comment)  
     Private  routine to format  FITS logical  card, return  a 80-character  
     string.  
interpreted function, defined at i/fits.i   line 1325  

             _fits_format_real(key, value)  
 
       -or- _fits_format_real(key, value, comment)  
     Private routine to format FITS real card, return a 80-character  
     string.  
     Note: FITS standard imposes that the ASCII representation of a real  
           number makes 20 characters;  the full precision of 64-bit values  
           can not be represented with this restriction.  
interpreted function, defined at i/fits.i   line 1352  

             _fits_format_string(key, value)  
 
       -or- _fits_format_string(key, value, comment)  
     Private routine to format FITS string card, return a 80-character  
     string.  
     Note: enclose input string in quotes, replacing each quote in input  
           string by 2 quotes.  Since opening quote should appear in  
           column 11 and closing quote in columns 20 to 80 of the FITS  
           card, make sure that string is not longer than 68 characters  
           (too long strings get silently truncated).  
interpreted function, defined at i/fits.i   line 1383  

             _fits_get_cards(fh, cards, ids)  
 
     Stores  in  variables CARDS  and  IDS  the  FITS cards  and  numerical  
     identifiers from header in FITS  handle FH.  The returned value is the  
     number of FITS cards (including empty ones).  
interpreted function, defined at i/fits.i   line 1284  

             _fits_id(hdr)  
 
     Return array  of numerical identifier  for FITS header data  HDR which  
     must be  an array(char, 80,  N).  Any invalid  FITS key will  have its  
     identifier set to -1.

     Numerical  identifers of  common FITS  keywords. If  you  experiment a  
     strange behaviour  of FITS  routines, it may  be because one  of these  
     values get corrupted;  in that case, just run  subroutine fits_init to  
     reinitialize things.  
keyword,  defined at i/fits.i   line 2763  

             _fits_id_special  
 
     Private  array  of  all  numerical  identifers of  common  FITS  keys:  
     "SIMPLE",  "BITPIX",  "NAXIS", "END",  "",  "COMMENT", "HISTORY",  and

             _fits_key(id)  
 
     Private routine used by fits_key, only  useful if ID is a valid scalar  
     numerical identifier.  
interpreted function, defined at i/fits.i   line 2654  

             fits_match(fh, pattern)  
 
     Return array of int's which are non-zero where FITS card names in FITS  
     handle  FH  match PATTERN.   PATTERN  must be  a  scalar  string or  a  
     numerical identifier.  As a  special case, if  PATTERN is of  the form  
     "KEYWORD#" (i.e.  last character of  PATTERN is a '#'), then any human  
     readable integer will match the '#', e.g. "NAXIS#" will match "NAXIS3"  
     and "NAXIS11" but not "NAXIS" nor "QNAXIS4.  
     Global/extern  variable  _fits_match_id  is  set  with  the  numerical  
     identifier of PATTERN (without last '#' if any).

             fits_parse(card);  
 
       -or- fits_parse(card, id);  
     Return value  of a single  FITS card (CARD  is a scalar  string).  The  
     type of the scalar result is as follow:  
        - string for a string or a commentary FITS card  
        - char ('T' for true or 'F' for false) for a logical FITS card  
        - long for an integer FITS card  
        - double for a real FITS card  
        - complex for a complex FITS card  
     In order to save a call to  fits_id, if ID is non-nil it is assumed to  
     be the numerical identifier of the card, i.e. fits_id(CARD).  
     The   comment  part   of   CARD  is   stored   into  external   symbol  
     _fits_parse_comment which is a string (possibly nil) for a valued card  
     and void (i.e. []) for a commentary card.  
     If the  SAFE keyword is true,  the routine returns an  empty result in  
     case of error.

             _fits_strict
