Well I used Algol60, 68, Fortran II, IV, Basic before C was invented in
1972. I don't remember having to take care of the registers. I'm
probably senile though :)

I used Pascal soon after it came out, I don't know if that was before C.

Certainly CPL, B & BCPL were used/known by the early Unixers (Thompson,
Ritchie, McIlroy kernighan et al.) and these preceded C. None of these
languages required explicit register allocation.
