| 34 | <p>The keyword <b><font face="Courier New">or4b</font></b> belongs to the family of the bitwise operators operating on <font face="Courier New"><b>bitstring</b></font>s, <font face="Courier New"><b>hexstring</b></font>s | |
| 35 | or <font face="Courier New"><b>octetstring</b></font>s of equal length. It performs the following operation: for each corresponding bit position, the resulting value is 0 if both bits are set to 0, | |
| 36 | otherwise the value for the resulting bit is 1.</p> | |
