Thanks Nenad, your comments are of great help for me.
My code is indented, but with tabs... wich have disapeared in the mail.
Sorry, i'll take care about this for next postings.
As you sugest, a next release will be a /View one... but now i don't know
how to make widgets move on a layout : i've just started to learn /Core and
/View. To learn, i'm also writing a webpage checker. The /Core version is
working, and i'm curently "dressing" it with /View. I'll post it here if i'm
not boring you with my scripts.
The actual /Core version stay below... but haven't yet been modified
regarding of Nenad's comments... except for my indentation, that i've tried

print "DATAFILE IS NOT ACCESSIBLE... creating one"
;### go to the website - work only within /View
goweb: func [i] [browse pick webdata/:i 2]
