you can use the following Program to access R0 to R7 registers in Keil C


{

unsigned char R0Val;

_asm

MOV A, R0
MOV _R0Val, A

_endasm

}

OR

{

unsigned char R0Val;

#pragma ASM

MOV A, R0
MOV _R0Val, A

C variables have to be prefixed by '_' or underscore character, to be accessible in the assembly section of the C code.
