Webloop decrements the count register; the flags register remains unchanged. Conditions are checked for by the particular form of loop you used. If the conditions match, a short jump is made to the address specified by the disp8 operand. The range of the disp8 operand, relative to the current instruction, is +127 decimal bytes to -128 decimal bytes. Webjump short or near; displacement relative to next instruction . jump far (intersegment; 4- or 6-byte immediate address . jump if condition is met; displacement relative to next instruction. Description. The jmp instruction transfers execution control to a different point in the instruction stream; records no return information.
