Thread: [Objectscript-users] Embedding examples

Hi,

in the examples of embedding some things not work, but may wasn't errors



-------------------------------------------------------------------
      Value val = OscriptInterpreter.eval("var foo = 1;", a);
      System.out.println("val= " + val );
      //this example returns NULL, when you  done  
OscriptInterpreter.eval("var ...") always returns NULL


      val = OscriptInterpreter.eval("foo = 1 + 4;", a);
      System.out.println("val= " + val );
      //here  returns   val= 5


-------------------------------------------------------------------


Greetings.

it is for the same reason that you can't do:


    a = var foo = 1;

"var foo" is a declaration rather than an expression.

If you want something that returns a value, and declares a variable,  
you can do something like:

   OscriptInterpreter.eval("var foo = 1; foo;");

the second statement after the ";" is an expression... the eval()  
should return the result of the last statement.
