it was:

Substituted and it ran. But with a serious problem with the output.
What is the problem? What is your "solution".
What I did was:
Put a halt instruction in the loader card.
,008015,022029,036040,047054,061068/039,072001.333333B068000N0000001040BOOTSTRAP
Then at the halt, ran single step. Found that the ZS instruction to clear word mark at
Location 540 was being interpreted by the simulator as a ) rather than the crazy square
which is not on my keyboard.
I went to the welcome.ocl file CHAR DECK ENTRY, and swapped the crazy square
With the ) which. It worked.
I’m sure there are other explanations.
