1. You said you didn't understand the jump, I think you didn't understand test ECX, ECX and test eax eax
the test instruction performs an and operation on the target and source operands, affecting some flag bits, such as ZF. Test ECX, ECX is to test whether the value of ECX accumulator is 0. If it is equal to 0, jump. The test instruction is a bit like the and instruction, except that the and instruction changes the value of the target operand while affecting the flag bit, while the test instruction only affects the flag bit
do you understand what I said? hey...
