Reverse everything after "He" example:
$binary = Pack("z0", "Hello World!") BinaryReverse($binary, 2) println( "Binary HEX: '" . BinaryStr($binary, ",") . "'" ) println("The binary size is: " . UBound($binary) ) For $i In $binary println( "Byte: " . $i . " | Hex: " . Hex($i) . " | Char: " . Chr($i) ) Next $String = Unpack("z0", $binary) println("Full string: " . $String)
Reverse the "World" part example:
$binary = Pack("z0", "Hello World!") BinaryReverse($binary, 6, 5) println( "Binary HEX: '" . BinaryStr($binary, ",") . "'" ) println("The binary size is: " . UBound($binary) ) For $i In $binary println( "Byte: " . $i . " | Hex: " . Hex($i) . " | Char: " . Chr($i) ) Next $String = Unpack("z0", $binary) println("Full string: " . $String)
