Hi people,

I've a question concerning the memory managment by the Keil compiler.

I'm linking building in SMALL model.
When reading the LST files, I can see that there is some bytes in the DATA segment. These datas seems to be the declarations made in the prototypes functions.
I mean that by writing this :
void Rectangle (U8,U8,U8,U8); // with U8 = unsigned char
then I've 4 overlayable bytes in DATA segment in the LST file.

The problem is that with many functions, the DATA segment becomes full and the stack crashs !

1. is there a way to change the declaration included in a prototype function to XDATA ?

2. More generally, when writting in C, is there a way to automatically declare a variable in XDATA without writting 'xdata U8 variable;'

Regards
