Sorry... I responded to Dave's email before seeing this one!
The main method must remain static or the X10 compiler won't recognise
it as the program main method.
However to call an instance method on Test, you need an instance of the
class. Therefore:
public static def main(args: Array[String](1)) {
val test = new Test();
finish for(var k: Int =0; k< 5; k++) {
val kk = k;
async test.funcWorker(kk );
}
Console.OUT.println("I am done " );
}
It is certainly more difficult to learn X10 without a background in
Java, but it's not impossible. The Programmer's Guide is a good start
(http://x10-lang.org/documentation/practical-x10-programming/programmers-guide.html).
Wherever possible you should learn from good examples that are
available, like the sample codes that come with the distribution
(~/x10-trunk/x10.dist/samples) and
http://x10-lang.org/documentation/code-examples/small-examples.html . I
also distribute a number of small samples with ANUChem
(https://sourceforge.net/projects/anuchem/) - see the samples subdirectory.
Cheers,

Thanks for your reply. However, even after making it a var, I get
complaint:
/Cannot access a non-static field field Test.currentWorkCounter:
x10.lang.Int <http://x10.lang.Int> from a static context
/
And to avoid it, I will have to make other two functions as
non-static, but then the whole program does not run properly and it
complains:
/x10c++: No main method found
1 error.
/
Please help me, since I am not from Java background hence I am getting
such errors. Thanks.
Thanks and Regards

Hi,
"val" roughly corresponds to "final" in Java (or const in C++)
To declare an instance field you want to be able to modify you
need to use "var"
var currentWorkCounter: Int =-1 ;
