All: Something fundamental about complex number initialization I am 
failing to understand. I wish to define a complex number

	z=x+ I y where x and y are both reals. Can someone tell me the 
proper way to tell Mathematica that x, y are real so that Re[z] returns 
x and Im[z] returns y? Much appreciated, Jon.
