AC31 IW 62.12. bytes usage and jump without label

Hello Dear Colleagues, we are trying to decode some old AC31 code. Programmer is using only second two bytes of IW 62.12 (days of the month) in his code. Also there is one jump instruction without label. Could you please inform us what do we get from second two bytes from IW 61.12 and what do we get with jump without label (does it stop PLC program execution?), and why do we have 4 bytes for days of the month?
Thanks a lot in advance.

Hi,

JUMPS - if you are askin for 3-rd case, that is unconditional jump - it is always unconditional. AFAIK, it is not possible to have a jump without label
