Why is it inconsistent?

>> do [1]
== 1
>> do 1
== 1

Well, you just pointed out that DO is inconsistent as well. As to 
how harmfully unexpected that is is another question. It obviously 
confused Will. Such things can be a problem, because there can be 
a loss of information. You get the same output from two different 
inputs, which can't be reversed.

Thanks Anton 8-) my point was just that for a beginner in the cases 
block there is value and block to execute pairs, so it sounded logic 
 that adding /default I would also need to append a block do be "done" 
I was surprised that case for default accept any and not a block 
, not a problem for me but we needed some minutes to understand that.

It's not inconsistent. It's just the way it is. DO evaluates all 
the values in the block and returns the result of the last evaluation.

From my point of view If anything is inconsistent it seems to be 
when Rebol evalutes blocks.


If you enter a block in the console, it doesn't get evaluated but 
other values do.

>> [1]

== [1]

>> a: 
1
== 1

The block [1] was not evaluted, the word a was.


Though without this possible inconsistency using blocks would be 
a real pain.

not only a pain, it would ruin the foundations of how rebol works 
:-)

(The block *is* evaluated.  Its contents are not.)

>> do [[1]]
== [1]


The console does the outermost 'do, resulting in your first example, 
Peter

Thanks Anton and Izkata. It looks as though the explanation of Will's 
"inconsistency" is that switch evaluates the content of the block 
not the block.

Hello all I'm new to AltmE would like to ask some questions later 
on nice to meet you all

welcome! .-)

Welcome -- glad you finally made it after knocking in the doors (via 
REBOLtalk) for so long!

Welcome!

Welcome David, ask away.

Happy REBOLing!

Thanks guys

here is some code I have been working on (commented) but the start 
button is busted I want it to call the area box with the discalimer 
details & 2No further buttons, one to quit "Disagree" which is a 
quit command & "Agree" I want to CLS the page & start a fresh copy 
of the XP simulated window, the start button would then open a different 
menu here is the code (its not very elegant I'm afraid):

Oop,s tripple posted how do you delete I will satrt again

You can't delete, but that's ok.

I will have to be more careful sorry!

so, the area is supposed to be hidden and then be displayed when 
you click start?

Indeed yes, the area or box will contain the disclaimer details + 
the two additional buttons Agree & disagree yes

called from depressing the [START] button

Bit like the way Windows works but obviously this is a simulated 
approach

however when I click the [START] button nothing happens its busted

ok, showing and hiding faces are done with SHOW and HIDE. Example:


view layout [button "Start" [either a/show? [hide a][show a]] a: 
area]

in your code, you are writing button "Start" [disclaim], but there 
is no actual face set to that word.

I guess what you need there is:

disclaim: panel [at ...]

not:

disclaim: [at...]

ahh so panel is a function to kick start the reamining block of text 
+ Buttons?

Henrik is just ahead of me --- you have disclaim as block.

Also, maybe when getting started, dont worry about the absolute positionings 
(they'd need to be adjusted according to screen resolution anyway). 
This simplification of your code works for me: (note the unview/all 
to remove any previous instances):


  rebol [Title: "SOS-XP"]
  unview/all
  view layout [
  across
  
  disclaim: 

  area wrap font-color white {You use this program & batch files entirely 
  at your own risk,
due to the myriad of hardware/software configurations I cannot
without any certainty claim that you will not damage your system!
Always Always Always make a full system backup of your partition
before attempting to use SOS-XP & that you have tested the back

up so your are positive in your own mind you can make a recovery!} 
red bold 
   return
   button "Agree"
  return button "Disagree"]
  return
  button gray 50x30 "START" [disclaim]

  ; this is a small vertical button to make the xP start button look 
  more realistic.
  return button gray 3x30

  ; this is a digital clock to simulate the destop clock bottom right 
  on screen.

  return text "00:00" rate 1 black ;effect [gradient 0x1 0.0.150 0.0.50]
  feel [engage: func [face act] [face/text: now/time  show face]
]

I cobbled this together from the beginners tutorial stuff & glued 
it together

Copying is sometimes the best way.

There are some stray ]s in the code I just posted.....Sorry. This 
below really does work:


  rebol [Title: "SOS-XP"]
  unview/all
  view layout [
  across
  
  disclaim:

  return button gray 3x30

  return text "00:00" rate 1 black ;effect [gradient 0x1 0.0.150 0.0.50]

Yes sunanda that is nearly there but I am trying to retain all the 
background stuff/Gui the discalimer box pops up on depressing the 
[start] button in fact the discalimer stuff overlays the previous 
gui stuff

I copied your code into rebol/view & ran it to see?

I thought the XP simulated look & feel would make it easy for users 
to use the program

Sorry about messing you UI up! As Henrick says, you need a pane and 
to work with swapping between different panes.
Tutorial here:
http://www.rebol.com/how-to/subpanels.html

I used the postioning to force the overlay effect is that the right 
way of doing things?

Kewl much oblighed

I will read up on "panel" also

Many thanks Henrik

no problem

<I copied your code into rebol/view & ran it to see?>

A possibly simpler way is to copy it into the Windows clipboard, 
then this line in the View console:
     do read clipboard://

yes thanks

tried with the a combination of panel & unview/all then in this line 
of code:

button gray 50x30 "START" [view disclaim] -> inserted view but the 
start button is pushed to the top right of the screen/Window the 
[Start] button now closes the XP lookalike gui, opens the discalim 
area in a black box?

half off the page

or monitor screen should I say

but at least the [Start] button now works kewl

I will just have a read of the subpanel info link you have provided 
Sunanda BRB

(they'd need to be adjusted according to screen resolution anyway) 
this is interesting so waht  could be ok on my screen setup could 
be completely different on someone elses Umm

Screen resolution is easy to get.....And it may be your first foray 
into the 'system object:
      print system/view/screen-face/size

(easy to get, hard to find :-))
