/*     --------  ---  -------------------------------------------------- */
/*     NAME       I   Name of the symbol to be duplicated. */
/*     COPY       I   Name of the new symbol. */
/*     TABSYM, */
/*     TABPTR, */
/*     TABVAL    I/O  Components of the symbol table. */


/* $ Detailed_Input */

/*     NAME       is the name of the symbol to be duplicated. The */
/*                components associated with NAME will be given to the */
/*                new symbol COPY. If NAME is not in the symbol table, */
/*                no duplicate symbol can be made. */

/*     COPY       is the name of the new symbol. If a symbol with the */
/*                name COPY already exists in the symbol table, its */
/*                components are replaced by the components of NAME. */

/*     TABSYM, */
/*     TABPTR, */
/*     TABVAL     are the components of an integer symbol table. */

/* $ Detailed_Output */

/*     TABSYM, */
/*     TABPTR, */
/*     TABVAL      are the components of an integer symbol table. */
/*                 On output, the symbol table contains a new symbol COPY */
/*                 whose components are the same as the components of */
/*                 NAME. */

/* $ Parameters */

/*     None. */

/* $ Files */

/*     None. */

/* $ Exceptions */

/*     1) If the symbol NAME is not in the symbol table, the error */
/*        SPICE(NOSUCHSYMBOL) is signalled. */

/*     2) If duplication of the symbol causes an overflow in the */
/*        name table, the error SPICE(NAMETABLEFULL) is signalled. */

/*     3) If duplication of the symbol causes an overflow in the */
/*        pointer table, the error SPICE(POINTERTABLEFULL) is signalled. */

/*     4) If duplication of the symbol causes an overflow in the */
/*        value table, the error SPICE(VALUETABLEFULL) is signalled. */

/* $ Particulars */

/*     If the symbol NAME is not in the symbol table, no duplicate symbol */
/*     can be made. */
/*     If the symbol COPY is already in the symbol table, its components */
/*     are replaced by the components of NAME. */

/* $ Examples */

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

/*        books   -->   5 */
/*        erasers -->   6 */
/*        pencils -->  12 */
/*        pens    -->  10 */
/*                     12 */
/*                     24 */

/*     The code, */

/*     CALL SYDUPI ( 'books', 'tablets', TABSYM, TABPTR, TABVAL ) */

/*     produces the symbol table: */

/*        books   -->   5 */
/*        erasers -->   6 */
/*        pencils -->  12 */
/*        pens    -->  10 */
/*                     12 */
/*                     24 */
/*        tablets -->   5 */

/*     The code, */

/*     CALL SYDUPC ( 'desks', 'chairs', TABSYM, TABPTR, TABVAL ) */

/*     produces the error SPICE(NOSUCHSYMBOL) because the symbol */
/*     "desks" is not in the symbol table. */
