In my youth I had a ZX spectrum which had BASIC with line numbers and no renumber command. Sometimes when adding code I'd simply run out of line numbers so had to GO TO an unused block of line numbers, put the new code there and GO TO just after the original code. I've never quite recovered from that.

My first job out of university was maintaining a FORTRAN IV program on a PDP-11. The only control structures in that language was IF..GOTO and the arithmetic GOTO. You can still write readable half-decent code with that, with discipline. A DO loop is still superior for readability.

The horrors of BASIC with its spaghetti of GO TO or its mess of PEEKs and POKEs are a justification for permabanning that style of programming -- but a decade of typing in listings from magazines inspired the generation the brought us the web and pocket phones. Maybe it wasn't such a bad thing after all.

You had a FORTRAN compiler that didn't have DO loops? I'm dubious.

Reminds me of those logic games that operate in (virtual) physical space

The feeling being squished into a corner by your own rat's nest is really something.

Reminds me of ROM hacking. Overwriting an instruction inside a function with a branch to unused memory and jumping back later is an easy way to get extra space for the patch you want to write.
