[Coco] Assembler question

[Helio Emery Jr.]

Hey all,
 
I found what was doing.
It turns out it was a silly beginners mistake.
I was addressing a constant using U register indirect addressing, instead of pcr indirect addressing.
This is one of the things that makes an assembly programing much more dificult to learn.
The compiler does not help with this kind of mistakes...
And my program is now with some 300 lines of code, so it's not always ease to see those mistakes while learning.
 
Anyway,
Thanks everybody for helping a newbee.
Now the program works as it should.
See you soon here,
Helio

Ok, so using either calls should guarantee the video going to graphics mode, but it doesn't...
Right now, this is the only way I know of changing from character mode to graphics mode in OS-9.
Anybody knows any other way?
 
The strange thing is that it works in C (but need to flush the buffer), and using DISPLAY directly from the OS-9 shell, but isn't working in Assembler.
 
Any ideas?
Thanks,
Helio
