   VARIABLE  I/O  DESCRIPTION

   item       I   Item to be removed. 
   set       I/O  Removal set. 
 

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.  Trailing blanks in item are not significant.


   set         is a CSPICE set.  set must be declared as a character
               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
      character, 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.
 
   3) If the input string pointer is null, the error SPICE(NULLPOINTER)
      is signaled.

Examples

 
   1) In the following example, the element "PLUTO" is removed from 
      the character set planets and inserted into the character set 
      asteroids. 

         #include "SpiceUsr.h"
                .
                .
                .
         /.
         Declare the sets with string length NAMLEN and with maximum
         number of elements MAXSIZ.
         ./
         SPICECHAR_CELL ( planets,   MAXSIZ, NAMLEN );
         SPICECHAR_CELL ( asteroids, MAXSIZ, NAMLEN );
                .
                .
                .
         removc_c ( "PLUTO", &planets   );
         insrtc_c ( "PLUTO", &asteroids ); 


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

Restrictions

 
   1)  String comparisons performed by this routine are Fortran-style:
       trailing blanks in the input set or key value are ignored.
       This gives consistent behavior with CSPICE code generated by
       the f2c translator, as well as with the Fortran SPICE Toolkit.
      
       Note that this behavior is not identical to that of the ANSI
       C library functions strcmp and strncmp.
