Isn't it because the line number is 16-bit unsigned int?

Great clue. Thanks!

RENUMBER takes maximum parameters of 32767 and 255.

But line numbers wrap! So if you do RENUMBER 32767,1 then your line numbers will go:

This is even more interesting, 32767 is the max signed 16-bit int. And it wouldn't wrap to 0 after that for sure.

Btw does it allow 0? Amstrad's BASIC does not (oficially).

I no longer have an Acorn Electron, but using ElkJS (https://elkjs.azurewebsites.net/) I did:

  >0 REM
  >10 REM

  32767 REM

  >LIST
      0 REM
  32767 REM
      0 REM
