Shawn,

Thanx for your reply.
I fully understand (i think) your remarks and agree with all of them.
The code I provided was just as illustration of the potential pbs I previously had remarked in my scripts and the console messages should of course be 'remarked' in an exploitation context.
I also introduced them for comments purposes for all of you to test/read.
As I previously wrote, all sorts of remarks from you would have been well appreciated.
I just wanna add that I wanted to make these precisions, because I felt that this topic was adequately placed in FAQ section for everyone, but could have 'as is' induce, one day or another, some puzzling errors.
Thanx again.
