KEIL C Command for RR and RL commands
'C' is a High-Level programming Languges (HLL) - it does not have "commands"
I guess that the "RR and RL" you refer to are some kind of processor instructions - but what processor?
But trying to predict machine instructions from 'C' source is fundamentally flawed and doomed to failure - see: www.8052.com/.../182535 (not specific to the 8052).
