Undefinitional binding - meaning it's not bound until you define 
it

...but that is not true, in fact

yeah there is a default binding during the loading,; I forgot...

yes, that is the problem, as well, as the problem of a function inside 
a function, etc.

The important process to make people understand is how lexical binding 
is faked by rebinding code over and over again as more nested contexts 
are defined.

infinite binding ?

It is really quite similar to what a compiler for a language with 
lexical scoping does internally, but we do it at runtime instead.

boundless binding :-)

Nested binding, it's my last proposal

Bye Folks

Me too, good night

Hi, is anyone familiar with Frank Sievertsen Telnet protocol scheme 
please?

I am trying to use it at a really basic level at first, just issueing 
the commands manually, but I think I am missing a trick or two.
this is what I am doing
port: open telnet://192.168.2.2/
t: copy port
print t


This shows me that I connected ok & got a password prompt, however 
I cant seem to work out how to send a string to the session & read 
the response. Any suggestions much appreciated. Thanks.

oops

I haven't looked at that in a looooooong time. I hope someone else 
can chime in and help.

Can you post what you're doing now, that isn't working?

e.g. are you using INSERT on the port?

May the commands be terminated with crlf

Hi, I had to drive 100 miles to pick up my son nexpectedly.  So my 
apologies for not responding straight away. Thanks very much for 
your responses.

Gregg, I am not doing anything to send data to the session because 
I dont know how to I am afraid. 

you mention INSERT, but even after looking at the telent.r code I 
am afraid I can work out what to do.


Steeve, the target device is a CIsco router so I think it would be 
happy with crlf or just cr

I am afraid I will have to be off to bed now, but hopefully a few 
small pointers will get me thinking in the right direction.
Thanks

I was confused by the insert function in the telnet scheme vs the 
use of INSERT in rebol but I have discovered that
insert port "username" 

does what I was trying to do, looks like I need to sort out the crlf 
issues but I think I am getting somewhere with it now.   

I am also unable to identify the method to disconnect, the telnet 
RFC mentions an "Interrupt Process" code 244, bit I dont see that 
implimented in the code..   Thanks.

Sounds like you're getting started Mike. Read the Core docs on ports, 
though I don't know how the telnet scheme maps certain things. Basically 
know that you can use READ and WRITE as high level ops on HTTP ports, 
but you may need to use lower level calls like INSERT and COPY to 
write and read data, and UPDATE may be needed as well in some cases.

Thanks Greg.   I didnt realise the Telnet scheme "port" concept was 
a Rebol generic thing, I mistakenly thought it was specific to the 
undocumented telnet scheme.   Looks like I need to do a close port

This is great, I am now getting somewhere.  Thanks again for your 
help.  

Will R3 impliment telnet as a native? Or is it too soon to ask?

It will be one of those DIY things i suspect

Question from ThomasP : 
how can I create a local SMTP server?
the SMTP server should run in the background, I just do:
set-net [127.0.0.1] to send my mail
I find simulator SMTP server on the web, but no real server.

Hu ? Just download a free one

use Cheyenne

which is also free :)

Hi,so i am quite new to the rebol community and have been assigned 
a project to work on.So to be frank i started reading rebol 2 days 
ago and i am quite confused since i worked with c++ before that.I 
am stuck at flow control and operators(sad i know).So basicaly i 
thought of when i moved from delphi to c++,basically if one of you 
guys can provide me with a rebol version of this small program i 
whipped up(flow control number check-the basics) it would be of great 
help to me,so here is my program and thanks in advance.
    

It inputs an integer number n and outputs the sum: 1+22+32+...+n2.I 
use input validation for n to be positive.
#include <iostream>
using namespace std;
    
int main()
{
     int n;
     cin >> n;
     if (n < 0) return 1;
     int sum = 0;
     int i = 0;
     while (i <= n) sum += i*i;
     cout << sum;
     return 0;
}

welcome to REBOL Martin , C++ to REBOL is probably the biggest jump 
you can make, but I'm sure you'll see the light in the end  ;-)


If your feel like REBOL is breaking the rules (those which you are 
used to in other languages), in fact see it more like, there are 
much *less* rules in REBOL.


although this freedom is dauting at first, I hope you'll come to 
appreciate it.

I'll give you a convertion in a few secs...

welcome to REBOL :-)

wow thanks alot maxim that would really help me get my act together 
it`s just that basic flow control and inputs are my weacknesses in 
this langueage

oh and oops the code does: 1+2^2+3^2+...+n^2

yeah my bad :D

thanks for the worm welcome

yea.. hehe I was wondering  ;-)

well copying from linux does that to you

in the above you use   cin   ...   do you expect the input to be 
piped ?

piped?

basically c input

it inputs a vallue for a varriable

ok.

this >> is input and << is output

yeah.. I don't use the C++ console ops a lot, I do C mainly.

but here goes...

n: to-integer ask "enter a number"
if  n < 0  [quit/return 1]
sum: 0
i: 0
while [ i <= n ] [ sum: sum + probe (i * i)  i: i + 1]
print sum

basically when you have cin>>n it awaits a vallue to be inputted 
in the console window

rebol returns 0 by default when you are the end of a script... so 
no need to add it at the end.

aha

ok so i just dont understand 2 lines of the code

sum:0

i:0

note, I added a little probe which prints the value at each step.


I did this to show you one powerfull aspect of REBOL... you can insert 
functions like *chains*
