Best way to do it, in my opinion. :-)

To specifically find the words in the VID dialect: probe system/view/vid/vid-words

There are several methods that I've seen proposed. The one I use the most is simply perusing the source. If I recall, the way to peruse /View source is through a text printout like so: ;boot to the console mode of /view echo %view-vid-1.2.txt print mold system/view echo none This method was adapted from Larry Palmiter. Then read to your heart's delight. To specifically find text-list, search for that word. Some faces' words are sprinkled through-out, so searching for the case-constrained name is better, like TEXT for text face.

Almost too many to mention.;-) These are the two official ones: http://www.rebol.com/docs/easy-vid.html http://www.rebol.com/docs/view-guide.html

I understand what you mean, kind of like the pack command in Tcl, etc. You may need to undergo a small paradigm shift. In this case, 'view is a function that displays the initial face layout. It kicks it off, so to speak. Later, after modifying faces in a layout, 'show allows *just* that face to be updated. It is more processing-efficient than going through 'view again.

Yes, actually there have been several, but I can't find any of them. If no one else answers this message thread, consider reasking this specific question again.

Here is one way: view layout [ across text "Name:" 100x24 right field "Your name" return text "Address:" 100x24 right field "Your address" return ] This was borrowed from one fof the references mentioned above. There are other ways, of course.

Robert Collect and submit: that's the "name of the game." Good luck, Robert. --Scott Jones
