Hi! Andy - I am not going to use C syntax in assembler and vice versa. Sometimes I have to write some parts of the program in assembler. Sometimes both modules (assembler and C) are using the same pin. In my opinion, when you declare i.e. sbit OUTPUT = P1^0 it is working like a variable in SFR register space. Isn't it? And I want to access it from assembler module like other external variables (placed in bit, data, xdata or code space). I am not going to use C syntax in assembler - I want to access SFR variable only!
But in this moment I know, it is not possible. I've got email from Raisonance and in this version of C compiler it is not possible to access SFR variables declared in C. But it will be soon :)
