Michael has the far better solution to avoid 'evail'
var global =3D this;
var whereAmI=3D"hither";
alert(global[whereAmI]); //displays 'Close by'
whereAmI=3D"yonder";
alert(global[whereAmI]); //now displays 'In the hills!'

Take care,
Jonathan"
Actually my point was about the unnecessary use of eval.
Michael and the other experts at comp.lang.javascript have helped me
many times, cwdjr too. And even though in this case his reply was more
directly related to and appropriate for the OP's question, who is to say
what is "far better". As we don't know the context with which this bit
of code will be used.
I could easily say that this:
var hither =3D "Close by";
var yonder =3D "In the hills!";
alert(hither);
alert(yonder);
is far more efficient and practical than what you offer, as the results
will be the same with a more simplistic approach. What I can't say
though is that this is the solution in any given situation without
knowing the application.
Later, Art.
