### SYNOPSIS

    FITSCard ft_headinsl(FITSHead fits, char *name, int n, int lvalue, char *comm, FITSCard here);
    FITSCard ft_headinsi(FITSHead fits, char *name, int n, int ivalue, char *comm, FITSCard here);
    FITSCard ft_headinsr(FITSHead fits, char *name, int n, double dvalue, int prec, char *comm, FITSCard here);
    FITSCard ft_headinss(FITSHead fits, char *name, int n, char *svalue, char *comm, FITSCard here);
    FITSCard ft_headinsv(FITSHead fits, char *name, int n, char *vvalue, char *comm, FITSCard here);
    FITSCard ft_headappl(FITSHead fits, char *name, int n, int lvalue, char *comm);
    FITSCard ft_headappi(FITSHead fits, char *name, int n, int ivalue, char *comm);
    FITSCard ft_headappr(FITSHead fits, char *name, int n, double dvalue, int prec, char *comm);
    FITSCard ft_headapps(FITSHead fits, char *name, int n, char *svalue, char *comm);
    FITSCard ft_headappv(FITSHead fits, char *name, int n, char *vvalue, char *comm);
    FITSCard ft_headdel(FITSHead fits, char *name, int n);

### PARAMETERS

- FITSHead fits - FITS header to insert, append or delete a card.
- char *name - Name of the FITS card.
- int n - keyword index number, if is zero no index number is appended to the keyword.
- int lvalue - Logical to format as a FITS value.
- char *comm - Comment for the new card.
- FITSCard here - Insert the new card after this card.
- int ivalue - Integer to format as a FITS value.
- double dvalue - Double to format as a FITS value.
- int prec - Precision for the value
- char *svalue - String to format as a FITS value
- char *vvalue - Raw value to format as a FITS value

### DESCRIPTION

These routines allow FITS cards to be inserted, appended and deleted by keyword value.

The insertion routines format a new card with the supplied keyword and value and insert it after indicated card. The append routines add new cards to the end of the header (before the END card).
