C4W_And()
Return the bitwise AND of two or more numbers
------------------------------------------------------------------------------

Syntax
C4W_And( <nValue1>, <nValue2>  [ , . . . , <nValueN> ] )   -->  nResult

Arguments
<nValue1>, <nValue2>, <nValueN> are numeric values.

Returns
The returned value is the bitwise AND of the values.

Description
This function performs a bitwise AND of the values, typically
to determine if a particular bit is set, or to extract one or
more bits.

The bottom 8 bits of a numeric value n can be extracted by
C4W_And( n, 255 ); the bottom 16 bits can be extracted by
C4W_And( n, 65535 ), or by using the C4W_LoWord() function.

Example
n = 130                  // 130 is the same as 128 + 2
? C4W_And( n, 2 )        // Result: 2
