^= Assignment

Purpose

Performs an exclusive bit-wise OR on two bit patterns, whereby the first pattern must be in an integer variable.

Syntax

i ^= j

i:ivar
j:integer expression

Description

i ^= j sets in the integer variable i only the bits which are set in i but are clear in j and vice versa.

The type of the operation is determined by the data type of the variable x. For integer variables GFA-BASIC 32 generates integer code.

Example

Local i%

OpenW # 1

Print Bin$(3, 4)  // Prints 0011

Print Bin$(10, 4) // Prints 1010

i% = 3

i% ^= 10

Print Bin$(i%, 4) // Prints 1001

Remarks

i=i Xor j is synonymous with i ^= j and can be used instead.
