Operator AND= (Conjunction and Assign)
Performs a bitwise-and (conjunction) and assigns the result to a variable
Syntax:
Usage:
lhs And= rhs
Parameters:
lhs
The variable to assign to.
T1
Any numeric or boolean type.
rhs
The value to perform a bitwise-and (conjunction) with lhs.
T2
Any numeric or boolean type.
Description:
This operator performs a bitwise-and and assigns the result to a variable (for conversion of a boolean to an integer, false or true boolean value becomes 0 or -1 integer value). It is functionally equivalent to:
And= compares each bit of its operands, lhs and rhs, and if both bits are 1, then the corresponding bit in the first operand, lhs, is set to 1, otherwise it is set to 0.
And= cannot be used in conditional expressions.
This operator can be overloaded for user-defined types as a member Operator using the appropriate syntax.
Note: Similarly to the operator '=[>]' (assign), the alternative symbol 'And=>' can be also used.

Examples:
' Using the AND= operator on two numeric values
Dim As UByte numeric_value1, numeric_value2
numeric_value1 = 15 '' 00001111
numeric_value2 = 30 '' 00011110
numeric_value1 And= numeric_value2
'' Result = 14 = 00001110
Print numeric_value1
Sleep
Dim As UByte numeric_value1, numeric_value2
numeric_value1 = 15 '' 00001111
numeric_value2 = 30 '' 00011110
numeric_value1 And= numeric_value2
'' Result = 14 = 00001110
Print numeric_value1
Sleep
Dialect Differences:
- In the -lang qb dialect, this operator cannot be overloaded.
Differences from QB:
- New to FreeBASIC
