The BIT menu
The BIT menu, available through the BASE (‚ã) provides the following
functions:
Functions RL, SL, ASR, SR, RR, contained in the BIT menu, are used to
manipulate bits in a binary integer. The definition of these functions are shown
below:
RL: Rotate Left one bit, e.g., #1100b  #11000b
SL: Shift Left one bit, e.g., #1101b  #11010b
ASR: Arithmetic Shift Right one bit, e.g., #1100010b  #110001b
SR: Shift Right one bit, e.g., #11011b #1101b
RR: Rotate Right one bit, e.g., #1101b 
#10000000000000000000000000000000000000000000000000
