World: r3wp

trying to compile the code now but the compiler from the site is 
a bit tricky

** Script error: n has no value
** Where: while
** Near: while [i <= n] [sum: sum + probe (i * i) i: i + 1]

:D

ok is the Near error a syntax error in the cycle?

the main difference in REBOL is that everything you can manipulate 
is a value, even functions and objects don't have a special syntax 
to use... they are values just like anything else.

there is no compiler...

hehehe... if you paste it directly in the console, the ask will intepret 
the next line as the answer  ;-)

then what am i using :D

:-)

so it triggers an error and n is never assigned any value  ;-)

yeah exctly i understood that

alemar - rebol is an interpreter ...

for the console, just replace the first line by 

n: 5

ok so where do you input the code(script)?

omg i am so wrthless

or you can make a function out of it.... right in the console.

ok so i am not doing this right

i am wrong at the verry beginning

so first things first

the console is for one-line inputs, if you want to type in your code 
directly. that interactive use of REBOL.


the way you want to do this, is create a script in notepad, and run 
the script from the REBOL console

how do i input the code as a whole in the interpreter

ahaa

try this:

does the script have any particular extension?

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
]

REBOL []

; right click this text area to copy the text

print "hello!"

then just:

my-func

save it as test.r

open a REBOL console and type:

do %/path/to/test.r

ok i get ** access error: missing port scheme: C

do C:\Users\alemar\Downloads\test.r

this what i typed in

rebol has its own path datatype...

so it would be 
do %/C/users/alemar/download/test.r

haha thank you so much for your patience guys

the % character before a string of text identifies the whole string 
as a file path...

ex:

>> type? %/C/users/alemar/download/test.r 
== file!

i really appreceate thet i just need to get this script running so 
i can grasp the basics

ok please don`t hate me i got this:

>> do %/C/users/alemar/download/test.r

** Access error: cannot open: %/C/users/alemar/download/test.r reason: 
-3
** Where: read either read-decode case load -apply- do

** Near: read source if find system/options/file-types type [data: 
de...

alemar, is your console a black DOS like console?

yes

ok, you are using REBOL 3. I suggest using REBOL 2 for now, as REBOL 
3's console is currently rather hard to use.

rebol3 alpha to be exact

ok

there won't be much difference at your learning level

thanks

at the downloads the only version 2 is REBOL/View 2.7 for Graphical 
Applications

will that do?

yep.

?
