Carl is notified.

well guys i have to say the community works and i am pleasntly impressed.I 
am checking the libraries now and trying to get the script to work 
since i am getting  ** Access Error: Cannot open /C/users/alemar/download/test.r
** Where: halt-view

** Near: do %/C/users/alemar/download/test.r                     
                                                                 
                   i will figure it out eventually and i can get 
to real programing in this langueage** Access Error: Cannot open 
/C/users/alemar/download/test.r

type:

exists? % /C/users/alemar/download/

hmm ok

you are doing the right thing. the question is if the script is really 
put there and if Windows allows reading there. I suppose you are 
using Win7?

yes i am

ooops... 

exists? %/C/users/alemar/download/

as a vmachine at the moment

Carl has fixed the site problem.

ahaaa i get --false

so i just gotta change the file location

the R2 console can actually act like a shell.


in the latest release (2.7.8) they added posix style shortcuts to 
the various file operations directly... so you can do:

>> cd %/C/users/alemar/download/
>> ls

yeah i got it now it is verry simple i just assosciated the.r extension 
with rebol :D

the advantage of opening the console first and executing do  is that 
any console i/o will remain in the current console...


if you just double click on a simple script, REBOL will open execute 
and close so fast, you might not even see it flash on screen!

aha

one of the advantages of being only 700kb  ;-)

ok but now when i start the file directly i get ** Syntax Error: 
Script is missing a REBOL header
** Near: do/args script system/script/args

my-func: func [] [
	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
]

ah yes.   scripts *must* start with rebol's header.

rebol [  ]

this is the body of the file

did you add the first line:

REBOL []

?

REBOL[]
my-func: func [] [
	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
]

like so?

you can see that Rebol is case insensitive  ;-)

yep

yep.  and don't forget to run the function at the end...

I'd also put a trailing ask ""

REBOL[]
my-func: func [] [
	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
]

my-func

ask "press enter to quit"

ok trying that as well,on a side note now the file does not start 
:D

sry my mistake

if you didn't put an ask at the end... just just didn't see it cause 
it closed to quicly.

works fine

yeah THAT i figured out from reading the libraries thanks alot guys 
you are great

if you press escape at any point,  the execution stops and you are 
sent to the console... try it.

cool

now try it with a negative number and the console will quit on its 
own (since I put a return/quit 1)

if you just want the function to return   remove the /quit 1

really nifty

/quit  is a  Refinement   a special function datatype which can be 
used in functions to supply additional parameters or instructions 
to a function.

ok i am beggining to love this language

so everything aside i really got into the basics thank you fo that

refinements is how REBOL gets away without any parens because the 
number of arguments is always known.

no problem... its always fun to have new users.  :-)

what do you mean always known

Be careful......Max is feeding you the red pill.

ex:

my-func [value /optional opt-value] [
	probe value
	if optional [
		probe opt-value
	]
]

my-func 33
my-func/option 22 "tadam"

because you added the refinement, it knows to expect an additional 
argument.

oops... 

my-func: func  [value /optional opt-value] [

thnks guys really gr8 community unfortunately my timezone says:go 
to bed or don`t bother at all" :D so i will leave the pc now but 
i will leave the chat on if i think os something in my sleep

alemar - where are you from?
