HiByte

Gets the second byte of the operand.

Syntax
	KeyPgPpdefine#define HiByte( expr ) ((KeyPgCastCast(KeyPgUintegerUInteger, expr) KeyPgOpAndAnd &h0000FF00) KeyPgOpShiftRightShr 8)

Usage
	result = HiByte( expr )

Parameters
	expr
		A numeric expression, converted to an KeyPgUintegerUInteger value.

Return Value
	Returns the value of the high byte of the low 16bit word of expr.

Description
	This macro converts the numeric expression expr to an KeyPgUintegerUInteger value, 
	then expands to an KeyPgUintegerUInteger representing the value of its second byte - 
	that is the most-significant (high) byte of the least-significant (low) 
	16bit word of expr.

Example
	Dim N As UInteger

	'Note there are 16 bits
	N = &b1010101110000001
	Print "N is                                       "; N
	Print "The binary representation of N is          "; Bin(N)
	Print "The most significant byte (MSB) of N is    "; HiByte(N)
	Print "The least significant byte (LSB) of N is   "; LoByte(N)
	Print "The binary representation of the MSB is    "; Bin(HiByte(N))
	Print "The binary representation of the LSB is    "; Bin(LoByte(N))
	Sleep

The output would look like:

	N Is                                       43905
	The Binary representation of N Is          1010101110000001
	The most significant Byte (MSB) of N Is    171
	The least significant Byte (LSB) of N Is   129
	The Binary representation of the MSB Is    10101011
	The Binary representation of the LSB Is    10000001
