hi Nigel, Chippie and all...

It's a very long time I didn't visit our forum. So sorry. But tonight, in France, not in Vietnam as I used to, I suddenly remember what I've learnt from you all, I just get back to see how it's now. No changes... no change.

It's always friendly as it used to be... I'm now not a student, and I'm helping younger students on PIC. I'm thinking of writing a tutorial in Vietnamese for my students. Thus, I'm coming back to learn from you all to enrich my tutorial. I hope i'm welcome?

Thanks you all...
