As Hai.juo has mentioned:
Variable Name - this is an identifier, keep it short and simple, makes coding a lot easier. Its only for programming, so needs not have anything fancy.
Variable Label - this is the nice frilly output reference which won't be used in programming.
var="The variable is called var";
label var "The label however here describes what var is for and is used in the output";
