Self Relocating Program
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
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.
