/*     VARIABLE  I/O  DESCRIPTION */
/*     --------  ---  -------------------------------------------------- */
/*     NAME       I   Name of the symbol onto which the value is */
/*                    enqueued. */
/*     VALUE      I   Value to be enqueued. */
/*     TABSYM, */
/*     TABPTR, */
/*     TABVAL    I/O  Components of the symbol table. */

/* $ Detailed_Input */

/*     NAME       is the name of the symbol onto which the value is to */
/*                be enqueued. If NAME is not in the symbol table, a new */
/*                symbol having the value VALUE is created. */

/*     VALUE      is the value to be enqueued onto the symbol, NAME. */
/*                The value is inserted in the value table after the */
/*                last value associated with the symbol. */

/*     TABSYM, */
/*     TABPTR, */
/*     TABVAL     are the components of an integer symbol table. */
/*                The symbol NAME may or may not be in the symbol */
/*                table. */

/* $ Detailed_Output */

/*     TABSYM, */
/*     TABPTR, */
/*     TABVAL      are the components of an integer symbol table. */
/*                 On output, the value table contains the new value */
/*                 in addition to the old values associated with the */
/*                 symbol NAME. The pointer table is updated to */
/*                 reflect the change in the dimension of the symbol. */

/* $ Parameters */

/*     None. */

/* $ Files */

/*     None. */

/* $ Exceptions */

/*     1) If the addition of the new value to the symbol table */
/*        causes an overflow in the value table, the error */
/*        SPICE(VALUETABLEFULL) is signalled. */

/* $ Particulars */

/*     If the symbol NAME is not in the symbol table, a new symbol is */
/*     created which has the value VALUE. */

/* $ Examples */

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

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

/*     The call, */

/*     CALL SYENQI ( 'books', 12, TABSYM, TABPTR, TABVAL ) */

/*     produces the symbol table: */

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

/*     The next call, */

/*     CALL SYENQI ( 'desks', 23, TABSYM, TABPTR, TABVAL ) */

/*     then produces the symbol table: */

/*        books   -->   5 */
/*                     12 */
/*        desks   -->  23 */
/*        erasers -->   6 */
/*        pencils -->  12 */
/*        pens    -->  10 */
/*                     12 */
/*                     24 */
