he was wondering, why it is true .... I found out after checking 
the type? blk/2, which is - word! .... my question is why it is word! 
and not logic! ?
blk/1 is integer!, why false here is not logic! ? anyone? thanks 
:-)

blk: reduce [1 false]   ;; to correctly evaluate the block contents
I guess it's analogous to:
  blk: [1 make object! [a: 1]]
  print blk/2
      make

blk: [1 #[false]]

ok, thanks ... I think now I understand ... yesterday I read about 
Haskell and functional languages ...
Bobik used str: "[1 false]" val: load str ... so basically, he "executed" 
(evaluated) string, he got block, but he forgot to do the same for 
block content - so here reduce comes in the play ...

It can be annoying because reduce does not have a /deep refinement 
-- so if you load nested blocks, you may need to do a lot of reduces 
to make it work:
   xx: reduce  load " [ false [ true]]"
   == [false [true]]
   type? xx/1
   == logic!
    type? xx/2/1
   == word!

I wonder if not being strongly typed (as Haskell claims they are), 
does not lead to almost untrackable bugs ... yesterday, working with 
debugger with our Ubicom CPU, I started to wodner, how we can live 
without the debugger in REBOL :-(

I''ve been caught-22 on that many times since I like to set my ini 
file definitions to be readable blocks and don't follow why other 
data types are correctly recognized e.g. blk: [1 12-feb-2006 $30.00] 
 but not true or false or Yes or No  without a reduce.  If you use 
blocks for the ini file settings you get caught by the reduce  e.g. 
if want this ini: [	clean-up-target-directory? Yes start-at 10:30:01 
first-day-to-run 12-dec-2006 last-day-to-run 31-dec-2006] reduce 
requires me to flag the words as 'words.

I tend to use nested objects as records stored in files. They suffer 
the same problem.

My solution is a single read function hat runs through reducing things.
Petr: having only 'trace or inserted 'print for debugging is like 
going back to the dark ages.
Better debugging would be a great step forward.

debugger? does a tool like this exist for REBOL? http://www.hmkdesign.dk/rebol/reblog/reblog.html
it's practically automated testing and probe on serious steroids 
:-)
Sunanda

Looks great!
Any release date?
Henrik

[3391]
I could release it now, but it's very, very buggy and it's not shielded 
from the program context
Sunanda

[3392]
You need to decide if you have the time now to deal with the bugs 
people will issue.  If not, wait til it is more stable.

consider it a flimsy prototype. requires list-view.r to be in the 
same path as the script
please don't submit suggestions or bug reports at this point
Pekr

[3396x2]
heh, cool :-)
Henrik - wrong link to list-view on the above reblog.html .... /reblog/ 
in the path should not be there ...

true and false - just use mold/all or save/all.
Pekr
9-Feb-2006
[3399]
well, imo Bobik has this block as some result of form field get-values 
function :-)
Gabriele

is the user typing true and false in?
Pekr
9-Feb-2006
[3401]
dunno, would have to ask him, once I catch him on icq ... but - I 
think it is OK, I explained to him why he needs to reduce the block 
...

pages like this one (in IE6 almost) http://www.hmkdesign.dk/rebol/reblog/files/category-3.html

is very bad right now
pekr, link fixed

Thanks Gabriele --- save/all neatly does the job.

No use to me though in several cases -- I support  applications that 
pre-date that refinement and run under older versions of core.
But it'll save me a chore in future apps.

hmm... seems I forgot there are some LIST-VIEW 0.0.29 only functions 
used in Tester. maybe I should do a release soon....

Another new feature that may help is the /ONLY refinement on REDUCE.
Very cool idea Henrik. Keep us posted.

Does any one have a tool for examining large objects?   I'm trying 
to find where things are defined in beer, and using an editor to 
browse the port object is not fun.  A sort of anamonitor for objects?
Gregg
10-Feb-2006
[3411]
port! values don't support the use of FIRST to get their words (AFAIK). 
At least I think that's what I ran into trying to support them in 
my old object browser.
Graham
10-Feb-2006
[3412]
where's your object browser Gregg?
Henrik
10-Feb-2006
[3413]
graham, did you try the object browser in Viewtop/Tools ?
Graham
10-Feb-2006
[3414]
Nope .. ;)
Volker

first is a port-operation.. Maybe it could use the default-words 
for ports.
Gregg

Under Developer/Users/Gregg. Run it under 1.3, it isn't happy under 
Link for some reason. I have some other versions floating around 
as well, but probably not too different from that one.

Graham, anamonitor can examine custom objects, not just the system 
object. You just need to type in a word/path which refers to the 
interesting object.
Graham

[3418]
Ok, good to know.
Anton

Yep, Anamonitor 2.0, next to the help button, there's a field that 
says "Name or command". Replace that string with "ctx-edit" for instance.
Gabriele

[3420]
i think anamonitor 3 can also examine ports, though i haven't tried
Anton
11-Feb-2006
[3421]
That would be pretty cool. Actually, as cool as anamonitor is, I 
don't use it much !  I probably should go exploring in it once in 
a while.

how to produce nice formated blocks? (with newlines where needed 
- not to have all values in onle line?)
hm, just found this: probe to-block {1 2^/3 4^/ 5} but I would like 
to insert newline formating when I produce block where I use repend
Sunanda

Hve you tried the
new-line
function -- available in recent versions of REBOL?
