I've finally created an App, but when I run it, all sprites/text in the screen is messed up.
Everything does work, it reacts correctly to buttons pressed, but whenever I use a sprite or do something like :
    LD     HL, $0006
    LD     (CurRow), HL
    LD    HL, Sometext
    b_call _PutS
the screen fills with random stuff.
The program doesn't crash, I can still switch between menus by pressing the correct buttons (I made the priogram, so I can navigate blind in it), but like said, text shown as above and sprites dont work.

The programm worked fine before being turned into an App, and most sprites seem to show in the upper left corner of the screen, instead of twhere they're supposed to be.

I've used AppDev to compile the .z80 into an app.
Has anyone encountered the same problem?
How to fix this?
As said befire, when I normally compile it, it works perfectly fine.
I'm exeeding the 8kB limit though, so that's why I'm turining it into an App.
If I need to include more info, just ask and I'll post it.

Some random info that might/might not be related to the problem:

When you do a Bcall, the address you are giving on your app page will be pointing to random OS data instead. What most APP developers do is write their own _PutS routine like this:

Líttle more info please, what it all does? :O
I'm a very newby programmer, so some more concrete info would be appreciated.
I do understany WHY the lot is messed up, thanx, though I still dont understand how to fix it.

And wha tyou said about the B_calls, does that count for ALL B_calls?
Because most, like b_call _RunIndicOff and b_call _GrBufClr seem to work fine...

Thanks anyway.

Well, your app page is mapped in at addresses $4000-$7fff. When you do a Bcall, the OS page with the routine is temporarily put there, so the data pointed to by HL will no longer be your text. That's why it works if you read your text data and display each character manually, since the OS will not be trying to read data from your APP.

I start to get it...
Though I still don't understand how your posted code can help.
What do I do in order to show sprited/text the right way?
I don't know what to do with the code you gave me, sorry :C

Instead of using:
 bcall _PutS
use:
 call app_PutS
and include the calcmaniac84 routine in the source code, of course.

I'll try, thanks alot.
Oh, where can I find that source code of calcmaniac?
Been googling without result so far...
Meh, I'll keep searching.

Replaced all the "b_call_PutS" with "call app_PutS" and included the small routine, but it's still messed up.
It does show the text now, though its in large font, and no where near where I want it.
Also, I can't applie it to sprites
I'm probably doing something wrong, but what's the normal way to display sprites/small text in an app where I want when I want?
Works when I use TASM to assemble and run it, but in an app its all still random junk on the screen, QQ.

For using small font there is a flag you need to change. (see asmin28days tutorial in the part about text display, I think)
There is other flag to write only to the buffer and not to the screen, so you copy the buffer to screen whenever you want.

For sprites a normal routine works, are you giving the right inputs for it?
If you have some bugs on the APPS, it can happen to show strange symbols in all the screen upon exit.

I don't know how to fix the sprite problem, but try this for your string:

    LD     HL, $0006
    LD     (CurRow), HL
    LD    HL, Sometext
    LD    DE, OP1
    LD    BC, ______     ; _____ is the length of your string in characters, INCLUDING the zero at the end
    LDIR
    LD HL, OP1
    b_call _PutS

I really have no idea what this will do for your app, but it fixed all my string problems for my app

I'll try, but you mean I load the number in BC that contains the number of characters +1?
So "Hello World!" would be
     LD     BC, 13
?

Yes, that's correct.
