34 <p>The keyword
<b><font face=
"Courier New">and4b
</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 a
1 if both bits are set to
1,
36 otherwise the value for the resulting bit is
0.
