Webshl BL , 2 The result 00000000B in BL is incorrect although the Carry Flag (CF) is cleared. Logical Shift Right Instruction (SHR) SHR shifts the rightmost bit of operand into the Carry Flag; the current value of the Carry Flag is lost. Each of the remaining bits is shifted rightwise and 0 is shifted into the leftmost bit of operand. Web3 Nov 2015 · This is the row number of the key pressed. Note that BL has been initialized to 1 at line 0491 and it is shifted left on line 049E in a loop. So it goes through 1, 2, 4 and 8 as …
