increments and decrements tape location 0 to write HELLO

increments and decrements tape location 0 in the following way 79-10+3-72+32 = 32 {space}

32-32 = 0; {NULL}

Reads {W} from input and then prints {W}
Reads {o} from input and then prints {o}
Reads {r} from input and then prints {r}
Reads {l} from input and then prints {l}
Reads {d} from input and then prints {d}
Reads {NULL} from input and then breaks loop since tape location 0 is now {0}

(then prints all of this text because it is after the '!')
