I'm not going to make any attempt to fix any of this in macro1, it is what it is.

This deserves some more explanation as to why such an arcane approach was necessary rather than just putting the (calculated) numerical value in the constant declaration.
My issues with this coding approach aside, I also wanted to point out some other documentation in the event that I missed it being called out in various other threads. There are a number of other PDP-1 documents associated with MIT in the https://bitsavers.org/pdf/mit/rle_pdp1/memos/ directory.
So all the history around the PDP-1 makes me wonder what instruction set(s) the PiDP-1 simulation is attempting to cover.
I can appreciate that it would be great to be able to recover and use as many historic programs as possible, but this may complicate the development tools. Right now I don't have a good feeling about the stability of those development tools.
I'm generally up for a good retro-computing archeological adventure as the next person, but being in the throes of another such adventure right now is somewhat exhausting.
[...]
I know, it sounds like a personal problem. Any ongoing thoughts on the instruction set issues and development tools would be appreciated to help talk me off the ledge.

I understand that talking me out the rabbit hole is not in your interest, but talking me off the ledge is important...at least to my mental health. I may have prematurely wound myself up about the state of the development tools without fairly investigating the behaviour myself. I'll have to get things running and take it a step at a time.

Hi Oscar,Re. your first comment: I'd be really grateful to know more about the sources you have in mind for computer history.
This mode of conversation was chosen because the psychiatric interview is one of the few examples of categorized
dyadic natural language comnmnication in which one of the participating pair is free to assume the pose of knowing
almost nothing of the real world. If, for example, one were to tell a psychiatrist "I went for a long boat ride" and he
responded "Tell me about boats", one would not assume that he knew nothing about boats, but that he had some purpose
in so directing the subsequent conversation.
I heartily recommend reading the paper itself and Weizenbaum’s subsequent book Computer Power and Human Reason. Especially for what they have to say about the current generative AI hype.

Did you see this? Not in depth, but an OK overview.
