Detailed_Input

 
   item        is an item which is to be removed from the specified
               set. item may or may not already be an element of the
               set.


   set         is a CSPICE set.  set must be declared as an integer
               SpiceCell.
 
               On input, set may or may not contain the input item 
               as an element. 
 

Detailed_Output

 
   set          on output contains the difference of the input set and
                the input item. If the item is not an element of the
                set, the set is not changed.
 

Parameters

 
   None. 
 

Exceptions

 
   1) If the input set argument is a SpiceCell of type other than
      integer, the error SPICE(TYPEMISMATCH) is signaled.
 
   2) If the input set argument does not qualify as a CSPICE set, 
      the error SPICE(NOTASET) will be signaled.  CSPICE sets have
      their data elements sorted in increasing order and contain
      no duplicate data elements.

Examples

 
   1) In the following example, the NAIF ID code of Pluto is removed from 
      the integer set planets and inserted into the integer set 
      asteroids. 

         #include "SpiceUsr.h"
                .
                .
                .
         /.
         Declare the sets with maximum number of elements MAXSIZ.
         ./
         SPICEINT_CELL ( planets,   MAXSIZ );
         SPICEINT_CELL ( asteroids, MAXSIZ );
                .
                .
                .
         removi_c ( 999, &planets   );
         insrti_c ( 999, &asteroids ); 


      If 999 is not an element of planets, then the contents of planets
      are not changed. Similarly, if 999 is already an element of
      asteroids, the contents of asteroids remain unchanged.
