hi,
I am new to SDCC. So I have some questions:
I have tried to port from the HiTech Compiler to SDCC.
I have declared bool variables:
bool bStartMM;
But SDCC comes up with the error
syntax error: token -> bStartMM ; column 16
Can anyone tell me please, what I make wrong?

Second:
I define the interrupt like this:

void isr(void) __interrupt 0 __naked

the same error occured. What is wrong?
I want to save the register in my code.

Thanks,
Kersten Tams
