NYT Wordlebot claimed I had two choices after my 3rd guess. Let’s see if it’s correct.

Self Relocating Program

Bruce Ediger

Once upon a time, I wrote a reasonably-strict-C89 C language program that “relocates” a function in memory and then runs it. That relocated function can relocate itself again, and run that copy, and so on and so forth.

My First Z80 Program

Bruce Ediger

I wrote a Z80 assembly program for my RC2014 Zed computer. I wanted to get a complete CP/M experience, so I used the CP/M 2.2 ASM assembler, LOAD relocator, and the DDT debugger.

I did cheat a little. Although I used the vintage RED editor for some text input, I also wrote some on my Linux laptop, and transferred to the RC2014 Zed via XMODEM.
