The Language Reference - Instructions - shr
The command this: shr shifts the contents of this right by one bit, shifting the rightmost bit (bit 0) into the carry flag, and making the leftmost bit (bit 7) a zero.
This is effectively division by 2. The zero and negative p-flags are modified accordingly.
