This is good with one variable, but what if I've got more variables? 
(e.g. three like in [face action event])

that is even easier. You justg

...you just need one properly bound variable and you can bind all 
other code using

...it

the problem is I don't know the name of variable so I was trying 
to get the new from function arguments, but I did not succeed

...get the name

That makes it difficult -- to bind one context to another, you need 
that word from the target context.  And functions don't have a 'self 
value like objects.  Nor are 'first and 'third values bound to the 
'second.

You could loop through the args (first) to find an appropriate word 
in the body (second), but you rely on and argument word being present 
in the function body -- does that make sense?

rely on and == rely on an

eg. I don't think it'd be possible to bind any block to -- a: func 
[x y][]

how can i know how many data is beeing uploaded to a site when using 
write ftp://........we have the read-net or read-thru to know how 
many data is beeing downloaded but what about writing ???

The UNIX cd command (a one-liner) in REBOL:

cd: func ['dir [file! word!] ][change-dir dirize to-file dir]

Now it's possible to type e.g.:
cd ..
cd rebol/view
etc.

Oops! cd rebol/view is not possible. :-)

cd: func ['dir [file! word! path!] ][change-dir dirize to-file dir]

NOW it's possible.

Question to myself: Why didn't I just write:
cd: func ['dir][change-dir dirize to-file dir]


There are many ways to write almost the same thing in REBOL with 
differenct side-effects. Good or bad!? I'm not sure, but it's fun! 
:-)

Another version, that will get to back to system/options/path, if 
'cd' has no argument:


cd: func ['dir [any-type!][either value? 'dir [change-dir dirize 
to-file dir][change-dir system/options/path]]

get to
 = "get you"

I put REBOL versions of many often used UNIX commands in a "unix.r" 
script, that I put in my rebol/view directory, so I can easily get 
to them, when I have to use the REBOL prompt. Just an idea for others.

An easy one:

pwd: :what-dir

There's also the group "*nix-sh" for discussing this.

Thanks!

*nix-sh is a private group ...

Any reason why I shouldn't make it public ?

IS there something terrible in it which annois some people, like 
hard religion or something? Else i see none.

ok now it's public.

How can I read any char from stdin?

system/console/input. if you need chars, not lines, set it to binary 
IIRC.

or [lines: false]? something like that.

using SET-MODES I think

Suggestion: ATTEMPT offers no possibility to provide a default value 
in case of failure. How about:

attempt/failure [2 / 0] "Invalid!"
== "Invalid!"

attempt [2 / 0]
== none

default-values: [a b c]

values: copy attempt/failure [read %values-file] default-values

2% more elegance? Or a debugging trap?

inbuild:
values: copy any[attempt [read %values-file] default-values]
Ladislav has something like your suggestion, called 'default.

not as clear, but I resorted to this when wanting to read out 0 when 
a numeric computation that is always positive failed:


first maximum-of reduce [0 attempt [2 / 0]] ; what's going on? .... 
oh :-)

attempt/default [2 / 0] 0 ; seems more clear

He did not patch attempt, its own. so
 default [ 2 / 0 ] 0  ; IIRC

default [read %values-file] "This file missing"

found it in RAMBO #3225...

one version is here, with explicit error-variable: http://www.fm.vslib.cz/~ladislav/rebol/default.r
- ah, you too.

interesting, i googled for "ladislav default", no "rebol" in it, 
42k hist, this one #4 :)

hist -> hits

google thinks rambo is a movie character. how quaint!

But always in the center of the action?

But why would an actor call himself after a broker?!

ups, no, rambo, not rugby. bug-squasher then.

Rebol will have sufficient fame when Stallone sues over the RAMBO 
name.

Maybe they join, the next RAMBO is about entering some bad computer 
and sqush all the bugmonsters there?

Does read/skip work in the new releases?

Doesn't look like it. I think file skip was removed because of moving 
to new Windows api.

When will open/seek be added? It was supposed to be there with new 
async core, we had async core for a while, but I do not remember 
anyone mentioning open/seek is there ...

you mean  "file seek"   or  "open/skip".

It was in the experimental releases, like View 1.2.57.3.1
Test with a line like:
	print copy/part read/skip %user.r 10 40    ;   compare 10 with 0
