BXOR (return bitwise exclusive OR)

Top  Previous  Next

 

BXOR(value,mask)

BXOR

Performs bitwise exclusive OR operation.

value

A numeric constant, variable, or expression for the bit value to be compared to the bit mask. The value is converted to a LONG data type prior to the operation, if necessary.

mask

A numeric constant, variable, or expression for the bit mask. The mask is converted to a LONG data type prior to the operation, if necessary.

The BXOR procedure compares the value to the mask, performing a Boolean XOR operation on each bit. The return value is a LONG integer with a one (1) in the bit positions where either the value or the mask contain a one (1), but not both. Zeroes are returned in all bit positions where the bits in the value and mask are alike.

BXOR is usually used to toggle on (1) or off (0) an individual bit, or multiple bits, within a variable.

Return Data Type:

LONG

Example:

!BXOR(0110b,0010b) returns 0100b  !0110b = 6, 0100b = 4, 0010b = 2

 

RateType  BYTE            !Type of rate

Female    EQUATE(0001b)   !Female mask

Male      EQUATE(0010b)   !Male mask

Over25    EQUATE(0100b)   !Over age 25 mask

Over65    EQUATE(1100b)   !Over age 65 mask

CODE

RateType = BXOR(RateType,Over65)  !Toggle over 65 bits
