It’s the machine language monitor on the 40-column screen of the Commodore 128 (or, more likely, an emulator of the same). I had a whole part about that, BASIC DATA statements full of numbers, and about how anyone with any sense actually used an assembler even back then in an original draft of my comment, but decided to keep it brief.
BASIC DATA statement? Wow you were so lucky. On my ZX81 we had to enter them as characters in a REM statement that was the first line of code so we knew their address so that we could execute it. Address Space Layout Randomization? Couldn’t work on the ZX81!
