I think this was a feature common to all the Microsoft BASICs of the era. I don't remember if the TRS-80 BASIC did it or not since most of the screen time I got on one of those was standing up at the display computer at the Radio Shack about a mile from my house, while I had a lot of time with Apple Computers. Apple's original Integer BASIC (written by Woz, natch) did not tokenize its input. I don't recall if it did any syntax checking at input because it was hard to get a hold of in the post AppleSoft BASIC era (I did eventually get a hold of a pirated copy on floppy disk that could be loaded into the himem region on a 64K Apple ][+ or //e but that was useful mainly for Woz's MiniASM that was in the part of ROM that was left over when he had Integer BASIC loaded).
