| <dt><em>Description</em>:<dd><code>DSHIFTL(I, J, SHIFT)</code> combines bits of <var>I</var> and <var>J</var>. The |
| rightmost <var>SHIFT</var> bits of the result are the leftmost <var>SHIFT</var> |
| bits of <var>J</var>, and the remaining bits are the rightmost bits of |
| <var>I</var>. |
| |
| <br><dt><em>Standard</em>:<dd>Fortran 2008 and later |
| |
| <br><dt><em>Class</em>:<dd>Elemental function |
| |
| <br><dt><em>Syntax</em>:<dd><code>RESULT = DSHIFTL(I, J, SHIFT)</code> |
| |
| <br><dt><em>Arguments</em>:<dd> |
| <p><table summary=""><tr align="left"><td valign="top" width="15%"><var>I</var> </td><td valign="top" width="70%">Shall be of type <code>INTEGER</code> or a BOZ constant. |

| If both <var>I</var> and <var>J</var> have integer type, then they shall have |

| BOZ constants. |

| be nonnegative. If <var>I</var> is not a BOZ constant, then <var>SHIFT</var> |

| <var>SHIFT</var> shall be less than or equal to <code>BIT_SIZE(J)</code>. |

| <br><dt><em>Return value</em>:<dd>If either <var>I</var> or <var>J</var> is a BOZ constant, it is first converted |
| as if by the intrinsic function <code>INT</code> to an integer type with the |
| kind type parameter of the other. |
