/* $ Detailed_Input */

/*     NAME       is the name of the symbol whose associated value is to */
/*                be set. If NAME has values associated with it, they are */
/*                removed, and VALUE becomes the only value associated */

/*                symbol is created, provided there is room in the */
/*                symbol table. */

/*     VALUE      is the new value associated with the symbol NAME. */

/*     TABSYM, */
/*     TABPTR, */
/*     TABVAL     are the components of a character symbol table. */

/* $ Detailed_Output */

/*     TABSYM, */
/*     TABPTR, */
/*     TABVAL     are the components of a character symbol table. */
/*                If NAME has values associated with it, they are */
/*                removed, and VALUE becomes the only value associated */
/*                with NAME. If NAME is not in the symbol table, a new */
/*                symbol is created, provided there is room in the */
/*                symbol table. */

/* $ Parameters */

/*     None. */

/* $ Files */

/*     None. */

/* $ Exceptions */

/*     1) If the addition of a new symbol causes an overflow in the */
/*        name table, the error SPICE(NAMETABLEFULL) is signalled. */

/*     2) If the addition of a new symbol causes an overflow in the */
/*        pointer table, the error SPICE(POINTERTABLEFULL) is signalled. */

/*     3) If the addition of a new symbolcauses an overflow in the */
/*        value table, the error SPICE(VALUETABLEFULL) is signalled. */

/* $ Particulars */

/*     If NAME has values associated with it, they are */
/*     removed, and VALUE becomes the only value associated */
/*     with NAME. If NAME is not in the symbol table, a new */
/*     symbol is created, provided there is room in the */
/*     symbol table. */

/* $ Examples */

/*     The contents of the symbol table are: */

/*        BOHR      -->   HYDROGEN ATOM */
/*        EINSTEIN  -->   SPECIAL RELATIVITY */
/*                        PHOTOELECTRIC EFFECT */
/*                        BROWNIAN MOTION */
/*        FERMI     -->   NUCLEAR FISSION */
/*        PAULI     -->   EXCLUSION PRINCIPLE */
/*                        NEUTRINO */

/*     The call, */

/*     CALL SYSETC ( 'EINSTEIN', 'GENERAL RELATIVITY', */
/*    .               TABSYM,     TABPTR,      TABVAL  ) */

/*     modifies the contents of the symbol table to be: */

/*        BOHR      -->   HYDROGEN ATOM */
/*        EINSTEIN  -->   GENERAL RELATIVITY */
/*        FERMI     -->   NUCLEAR FISSION */
/*        PAULI     -->   EXCLUSION PRINCIPLE */
/*                        NEUTRINO */

/*     Note that the previous values associated with the symbol */
/*     "EINSTEIN" have been deleted, and now only the new value is */
/*     associated with the symbol. */


/*     The next call, */

/*     CALL SYSETC ( 'MILLIKAN', 'PHOTOELECTRIC EFFECT' */
/*    .               TABSYM,     TABPTR,       TABVAL   ) */

/*        FERMI     -->   NUCLEAR FISSION */

/*        PAULI     -->   EXCLUSION PRINCIPLE */
