Hi, Both operators <- and = can be used to make an assignment. My question is: Is there a semantic difference between these two? Some time ago, I remember I have read that because of some reason, one should be given preference over the other - but I cannot remember the source, nor the argument, nor which operator the preferred was. What is the present state ? Is still one version better than the other, or is it only a matter of taste what to use ? thanks Thomas
