Hi,
I've a statement that draws a line in the window:
WinDrawLine (bounds.topLeft.x, bounds.topLeft.y + bounds.extent.y,
bounds.topLeft.x + bounds.extent.x, bounds.topLeft.y + bounds.extent.y);
At runtime, the values of bounds are:
topLeft.x = 0
topLeft.y = 62
extent.x = 160
extent.y = 80
The code runs fine on all on-debug ROMs on OS3.0, 3.1, 3.3 and 3.5. The code
also runs fine on debug ROMs of OS 3.0, 3.1 and 3.3. However, I always get a
bus error when I run it on the debug ROM for OS3.5. Can someone please
enlighten me?! Attached below the the asm code for anyone who can
understand. I don't have the slightest knowledge of assembly so I guess I
can't help myself there... :(
Regards,
Gee.
