/// # Brief I/O

/// ```text
///  VARIABLE  I/O  DESCRIPTION
///  --------  ---  --------------------------------------------------
///  NAME       I   Name of the symbol whose associated value is to be
///                 set.
///  VALUE      I   Associated value of the symbol NAME.
///  TABSYM,
///  TABPTR,
///  TABVAL    I-O  Components of the symbol table.
/// ```
///
/// # Detailed Input
///
/// ```text
///  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 with NAME. If
///           NAME is not in the symbol table, a new 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 double precision symbol table.
/// ```
///
/// # Detailed Output
///
/// ```text
///  TABSYM,
///  TABPTR,
///  TABVAL   are the components of a double precision 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.
/// ```
///
/// # Exceptions
///
/// ```text
///  1)  If the addition of a new symbol causes an overflow in the
///      name table, the error SPICE(NAMETABLEFULL) is signaled.
///
///  2)  If the addition of a new symbol causes an overflow in the
///      pointer table, the error SPICE(POINTERTABLEFULL) is signaled.
///
///  3)  If the addition of a new symbol causes an overflow in the
///      value table, the error SPICE(VALUETABLEFULL) is signaled.
/// ```

/// # Examples
///
/// ```text
///  The contents of the symbol table are:
///
///     DELTA_T_A -->    3.2184D1

///
///  The call,
///
///  CALL SYSETD ( 'ORBIT_ECC', 1.67125D-2, TABSYM, TABPTR, TABVAL )
///
///  modifies the contents of the symbol table to be:

///
///  Note that the previous value associated with the symbol
///  "ORBIT_ECC" has been deleted, and now the value 1.67125D-2
///  is associated with the symbol.
///
///
///  The next call,
///
///  CALL SYSETD ( 'EB', 1.671D-2, TABSYM, TABPTR, TABVAL )
///
///  modifies the contents of the symbol table to be:

///     DELTA_T_A -->    3.2184D1
