The ORA A instruction does not change the contents of the accumulator. It does, however, set flags to indicate something about the value of the accumulator. In particular, Z means the result is zero, N means it is negative, and P means it has an odd number of ones.
Because that is the way Intel designed the INX instruction of the 8085. The 8080 is also the same. INX increments (and DCX decrements) the 16 bit register pairs or BC, DE or HL, depending on what register pair you specify in the INX (or DCX) instruction. To check is the value is 0 after an INX (or DCX) instruction, you need to OR the values of the register pair into the A register. For example..... INX H ;increment HL register pair MOV A,H ; move H register into the accumulator ORA L ; Logical OR it with the L register JZ ADDR ; If 0 then jump to ADDR
