- The SSHHIIFFTTLL intrinsic function performs a left shift with zero fill of
- _i by _j bits. It accepts the following arguments:
-
- _i The value to be shifted. _i can be of type Boolean, integer,
- real, or Cray pointer.
-
- _j The number of bits to shift the value. Must be of type
- integer or Boolean. _j must be within the range
- 0 <= _j <=_s_i_z_e, where _s_i_z_e is the size, in bits, of _i. That
- is, if _i is a 64-bit object, _j must be within the range
- 0 <= _j <= 64.
-
- On UNICOS systems, an object is 64 bits. On UNICOS/mk systems, an
- object is 32 bits or 64 bits. On IRIX systems, an object is 8 bits,
- 16 bits, 32 bits, or 64 bits.
-
- SSHHIIFFTTLL is an elemental function. The name of this intrinsic cannot be
- passed as an argument.

- This is an outmoded routine. Refer to the _F_o_r_t_r_a_n _L_a_n_g_u_a_g_e _R_e_f_e_r_e_n_c_e
- _M_a_n_u_a_l, _V_o_l_u_m_e _2, for information about outmoded features and their
- preferred standard alternatives.
-
- The bit representation of the logical data type is not consistent
- among UNICOS and UNICOS/mk systems. For further details, see your
- compiler's reference manuals.

- SSHHIIFFTTLL returns a value of type Boolean on UNICOS and UNICOS/mk
- systems. It returns an integer result on IRIX systems.

- EEXXAAMMPPLLEESS
- The following section of Fortran code shows the SSHHIIFFTTLL function used
- in the case where _i is of type integer. The bit pattern of _i and the
- bit pattern of the result are also given. For simplicity, a 16-bit
- object is used.
