"X = X + Y" means "X[t+1] = X[t] + Y[t]" where t is time. Time had to be
omitted from the notation of the BASIC programming language because otherwise
the source code would consume a much larger amount of computer memory and it
would complicate GOTO and FOR/NEXT statements.

used := for assignment, different from = for equality comparison. -John]
