Numlist is a joke esolang invented by User:None1.
Every program is a list of integers separated by spaces.
An integer x tells the IP to move x cells forward, IP starts at left.
If the IP overflows, the program terminates. If the IP will underflow after an operation, the opposite number (the number of first instruction is 0) of IP after this operation will be printed as Unicode and the IP will move to the next instruction instead.
Examples
