>> convert to RR not RRC

Hi,

I need to put a statement in a interrupt routine to shift a variable right one-bit. Like this:

dat >>=1;

It generated assembly code like this:

MOV A,dat
CLR C
RRC A
MOV dat,A

What statement in C language sould be written to complete the shift operation but not effect the "C,carry" bit?

This is to save the "PUSH PSW", "POP PSW" instruction in my ISR. The inline assembly statement is not good to me, since I am not familar with it.

Thanks, John
