@Henrik, ok...

I really don't know where things should or shouldn't go.

we'll figure that out eventually.

so, the user clicks "Show Question" to see a question. then he clicks 
"Show answer" to see if he's correct?

that'll be wonderful. I've been banging my head on these issues for 
over a week.

@Henrik, yes.

ok, and the idea of "Soon" is?

....to move the current question to a forward location in the pool 
of questions becasue the user doesn't have the answer yet.

The user will then see the question again,.."Soon"

I see. And you save this, because you want to have the user start 
where he stopped from, when last quitting the program?

exactly!

is there a particular reason that you split the questions and answers 
in separate files?

since I was new to rebol/view and vid, I didn't know of a better 
way to make two streams of data, one going to questions and another 
to asnwers. The prospect of updating two sides of the same list seemed 
confusing to me hence my split.

ok. I think in general you will have an easier time not doing this 
split. Instead you can work on using the card data directly. Then, 
what you would save, would be a REBOL formatted copy of those card 
data. I think this will simplify your program.


you are already taking advantage of reading the cards with READ/LINES. 
when you parse that data, you can turn it into a record with two 
elements in each, the question and the answer. then by using SAVE/ALL, 
you can directly save this as your questions and answers, in the 
custom order that the user likes.

@Henrik, ok. there is allot in there.

yes, it might be too dramatic. perhaps it's better to save it for 
later.

I am not sure how to do these individual steps yet, but I actually 
do understand the gist of them.

there is a typo in line 54: quesiton-list.txt

@Henrik, ok. But I do want to explore the options you present because 
it meets my other goal of working with different data structures 
in rebol.

@Henrik, thanks!

I wonder why rebol didn't flag that...

it simply writes a new file, so the code is syntactically correct.

oh ok..

as for my writing above, an approach would be to load the cards file 
and parse it into a format that is comfortable to work with in REBOL.

ok

what about the issue of swapping though?

perhaps you can try moving back one element after swapping. that 
might put you in the correct location.

or perhaps use MOVE instead of SWAP

here is a cheap console version:

it does not work entirely the same as yours, but you can use it for 
inspiration. just ask, if there is something that you don't understand.

it will crash at the end, so I leave it as an exercise on how to 
fix that :-)

@Henrik, thanks. How does using MOVE update the original list?

going back to my question about using SWAP.

I see you moving it within the list but the file doesn't dynamically 
get changed using MOVE...

I get the following error and haven't a clue what is wrong. What 
normally causes this? Thanks.

** Access Error: Cannot open file.txt
** Where: forever
** Near: were: read/lines %were-file.txt

MOVE modifies the list like SWAP does, but does not require any adjustments 
to index.

** Access Error: Cannot open file.txt
** Where: forever
** Near: were: read/lines %were-file.txt


That is possibly because file.txt does not exist and you are trying 
to read it somewhere near that line of code.

@Henrik, I see. I will try to better trace the path the file takes 
to open. thanks.

I'm trying to trouble shoot this error I get, but not sure what it 
means:

** Script Error: button-press? has no value
** Near: do view button-press?

It means, that you use the button-press? variable in the above expression. 
But, you forgot to define that variable.

@Ladislav, I'm trying to use the VID dialect. This is how I start 
my definition of button-press?....

button-press: layout [ .....]

@Ladislav, I figured out my problem.  My typo.

thanks.

@Henrik, thanks for your help. I think I've figured out most of the 
code and how to apply it to my situation aka HW. My previous approach 
was totally confusing me.

@Henrik, do you have any advice as to the sort of things I can be 
learning if  I want to understand REBOL better? Like specific problem 
sets for instance.. The tutorials are good, but they don't seem to 
be getting across to me.

Is there a standard list of  what goes into the block following the 
REBOL flag? I'm thinking javadocs here. Thanks.

@Ladislav, thank you.
