Explanation
The function of JMP is similar to the function of CJ. CJ must be driven by a
contact whereas JMP does not have to be driven by a contact.
The pulse instruction JMPP is not supported.
Example
After address 0 is scanned, address N will be executed whether there is a
conditional contact before the instruction JMP (and whether the conditional
contact is ON or OFF), and the addresses between address 0 and address N
(P1) will be skipped.
