Go to technology,这一点在超级权重中也有详细论述

Объяснено

The compiler was QuickBASIC 3.0, QB30 to its friends. Safe to say it was not particularly good at optimizing the binary. Not that we should be overly surprised: BASIC is born to be an interpreted language, and most of its “compilers” just turn the code into an intermediate representation (P-code) and pack a virtual machine alongside it to create an executable. And yet: since this HELLO.EXE already requires us to provide a runtime module (BRUN30.EXE) we might expect the executable itself to be minimal, just carrying the P-code equivalent of the one source code line, plus the runtime loader. But, as it always happens, the devil is in the details, and reconstructing them took many days. Anyway, it was a fun experience, and it might help to enlighten QuickBASIC’s technology for the dozen people in the world that have interest in it.
