Hi Levente. Thanks for the answer, but I didn't understand. Which code do
you mean?

If you refer to:

[ true ] whileTrue: [ 1+1 ]

I am sending the message whileTrue: to BlockClosure and the message + to 1.
So, I don't understand.

In theory yes, but in practice no. Just look at the generated bytecode:

ahhhhh ;)
�

13 <71> pushConstant: true
14 <9D> jumpFalse: 21
15 <76> pushConstant: 1
16 <76> pushConstant: 1
17 <B0> send: +
18 <87> pop
19 <A3 F8> jumpTo: 13
21 <78> returnSelf

As you can see #whileTrue: totally disappeared, no message sends. There's a send for #+, but that's a B0 bytecode which will not do a real message send, because both the receiver and the argument is a SmallInteger.
Therefore your code won't send any messages.

Ok...I got it. But now I tested with this:

[true] whileTrue: [
Transcript open.
Transcript show: 'mariano'.
Transcript close.
]

With bytecodes:

33 <71> pushConstant: true
34 <AC 0C> jumpFalse: 48
36 <41> pushLit: Transcript
37 <D0> send: open
38 <87> pop
39 <41> pushLit: Transcript
40 <23> pushConstant: 'mariano'
41 <E2> send: show:
42 <87> pop
43 <41> pushLit: Transcript
44 <D4> send: close
45 <87> pop
46 <A3 F1> jumpTo: 33
48 <78> returnSelf

Now it should work, isn't it ?�� However, I still it doesn't interrupt the process :(

Thanks for the help levente.

Btw, you can turn CPUWatcher on from the Process Browser and see the CPU

usage of processes.

Yes, I tried this before but it happened the same....I tried to test it,
evaluating
[ true ] whileTrue: [ 1+1 ] �but it was not interrupted.

I also tried to click several times in the world but with no luck.

Thanks

Cheers
