I think the Pause is only needed in the second loop.

I think that I understand everything except of the Pt-Off(0,A++^8+Pic1

Except if you have a real 83+ (I mean not a new 83+.fr which is a 84+SE), I'd advise to close parentheses, brackets, etc. Keeping them open doesn't optimize anything in the compiled program and is just asking for bugs from the compiler (even though the compiler should work, but it's better not to tempt it)
I also see you didn't try my code because I made a typo when writing (forgot a ","), so it actually didn't do anything
I corrected it in my post.

Now, what does it do ?
Well, this
[001122334455667788]
is the same as this
[00]
[11]
[2233]
[445566]
[77][88]
It doesn't seem interesting that way, I know, I am just pointing (pun intended) out that you can write your data the way you want.

Now, this
[001122334455667788]→Pic1
[001122334455667788]
is the same as this
[00]→Pic1
[112233445566778800] .this is pointed by Pic1+1
[1122334455667788]
and the same as this too
[0011]→Pic1
[223344556677880011] .this is pointed by Pic1+2
[22334455667788]
etc.
And Pt-Off(0,,A++^8+Pic1) displays the sprite pointed by Pic1, then the one pointed by Pic1+1, ... then the one pointed by Pic1+7 and then we go back to Pic1.

Do you see better what it does ?
(or was it just the typo that prevented you from seeing it ? )

what do you mean?

i really don't understand what you are talking about...

what message are you talking about?

which ones are you referring to?

So yeah, appvariables....
I want to have them in archive (of course), and I wonder if it is possible, instead of un-archiving it, to create a copy of it in ram, leaving the original in archive?

yes, that is possible. You can use file.
 
For example, let say you have appvDATA in archive, and you want a copy in ram.
You can do :
GetCalc("appvDATA",Y0)
.Y0 is the function token, it specifie the file you want to put the appv in. You have 10 file (Y0-Y9)
{Y0-2}r->A
.A will hold the size of the appv, stored 2 byte before the start of the appv.
.Next line will create a temporary vars (delete at the exit) with the size of the appv
 GetCalc("tmpDATATMP",A)->P
 Copy(Y0,P,A)
.this is allowed, but not everything can be done with file. (like 0->{Y0}r)
.P is now the pointer to appv.

In this code, I didn't check if all process succed in there task, but you most likely want to check the return value of GetCalc (0 if there is an error)
Also, when you want to store back your appv, you should be able to use Copy(P,Y0,A) (but I am not sure of this) (and based on the fact that A and P are not destroyed)
 
EDIT : 

It specify the file you want to put your appv in.
It is logical the getcalc return you 0 if the appv was in archive, since it couldn't read it.
