ok, you have String A that looks like $4F,$01,$02,$04,$05 and String B which looks like $05,$04,$02,$01 and you want your output to look like $01,$02,$04,$05 right?  So what's the advantage of using String B?

I use just Str9. The name I need to store into Str9 is [Pointer - 7] until [Pointer - 6 - Name lenght] .
But I think I found a solution already. Thanks anyway. :)

It is redundant to get the NAME of the entry and then search the symbol table again to find the entry with that name using GetCalc()

The data pointer can be found at {entry-4}rr.  You can then add 2 to that pointer to skip over the size bytes in the data to mimic how the getcalc() works.

Ok, Ill use the VAT data pointer instead of Getcalc( .
I am having still trouble by outputting an Appvar Entry with the small font.
I thought this is possible:
Code: [Select]
.VAT2STR

{e9830}r -> P . VAT start Pointer

Repeat getkey(15)

ClrDraw
""[CE]"       "->Str9 . [CE] is the "..." Character for representing loading, then Space character by seven times

If {P}=21 . If current entry has type 'appvar'

For(X,0,{P-6}-1)
{P-7-X}->{Str9+X} . This doesnt work. :/ It should copy the entry name into Str9
End

Else . If the type isnt 'appvar' then Str9 is still "..."

P-{P-6}-7-> P . Go to the next entry

End

If getkey(3) and (P>=VAT end
P-{P-6}-7-> P
End

Fix 5
Text(1,1,Str9) . Str9 is always "..."

Dispgraph

End . Loop End

Fix 4
Return

first, I notice "{P-7-X+1}->{Str9+X}" should be "{P-7-X}->{Str9+X}" since P-7 is the first entry, not P-6, which is what yyou got by adding 1 back at the end... I'll go over it more later when I have time to see what els...

Youre right. I removed the mistakes from the code in the last post.
Here is a screenshot showing what happens if I output appvar names character by character with 4 pxl gaps.

Why do it character by character? Didn't you just have code for storing it and displaying it as a string?

@ Runer
Yes, thats what Im trying to do, but currently Im having trouble by copying the entry name into a string.

Code: [Select]
For(X,0,{P-6}-1)
{P-7-X}->{Str9+X} . This doesnt work. :/ It should copy the entry name into Str9
End
Seems like this code does nothing.

Well your code has no errors, but the problem is that your program is compiled as an application. Apps exist in ROM so they can't use self-modifying code, which is what storing to internal pointers like Str9 really is, so that's why that does nothing. What you need to do is instead allocate a section of safe RAM to hold the string and copy and display the string from there.

Oh, I see. I will probably go back to use programs for storing level data like I did at the start of this topic.
Thank you, Runer.

Wait, why are you going back to using programs? This isn't a problem inherent in the fact that level data is stored in appvars, it's a problem inherent in the fact that your main program is compiled as an application.

Or more specifically, trying to change a string while compiling to an application...

I wanted to output the entry name as a string to dont get pen moving problems like in the screenshot.
Program names are just Uppercase, so all font sprites would be have a defined width of 4pxl, so I could
output program names char by char without having to use strings. I think everything else would be not as efficient as this way, especially because I have to take a look on my remaining memory size.

Simply replace "Str9" with "L1" or some other free ram.  Then you can call "Disp L1" later.  Don't forget to add the null character at the end of the string.
