Hello,

I'd like to test a variable : if it is null, I assign a value to him
("toto", for example).
My scipt functions very well. Ex :

test=null;

if(test==null) {
test = "toto";
}

But[...] if the variable is not null but undefined, how can I program "
if test is undefined, I defined it and assign value "toto" ? "

Thanks.

You can put in

if( xyz == undefined ){

xyz = "isdefined now";

}

But xyz has to be declared somewhere as

var xyz;

For example put it in the initialize script.

If you do not do this you will get a runtime error as per the Rhino docs.
