The real question might be whether the compiler was smart enough to change var++ and var-- into ++var and --var when the initial values aren’t needed.
As compiler optimisations go, it’s a fairly obvious one, but it was 1974 and putting checks like that in the compiler would increase its size and slow it down when both space and time were at a premium.

Well, good news, the source code is right there. Someone can go check (it probably won’t be me)
I was going to guess the same regarding the time period.
