STJ instruction in line 03 resets this address. (It is conventional to denote the address of such instructions by ‘*’, both because it is simple to write, and because it provides a recognizable test of an error condition in a program, in case a subroutine has not been entered properly because of some oversight.

3. Read in 100 words from tape unit zero; exchange their maximum with the last of them; exchange the maximum of the remaining 99 with the last of those; etc. Eventually the 100 words will become completely sorted into nondecreasing order. The result is then written onto tape unit one. (Compare with Algorithm 5.2.3S.)
4. Nonzero locations:
OUT waits for the ...
