Hi,

Thanks, your suggestion give some shed of light to me ... :)

Since I am quite new to Python also,
I will need more in depth look on the StringIO class and
how to assign an object to the sys.stdout variable ... ;)

I will try it out, any help is greatly appreciated ...
especially if you're willing to make that "small apps" 
that you mentioned previously ... :)

best regards

 @&gt; Probably; what you can do is assign a file-like object to
