Thanks Phil! It is a good solution to use scalars.

But, on a side note, min() can work on one variable too

e.g.:

generate minv=min(variable1)

min() doesn't do what you think it does. It's more for this kind of thing:
gen newvar=min(var1, var2, var3)
or
gen newvar=min(var1, var1[_n-1])
or
summarize price
display min(r(mean), r(p50))

To get the lowest value of the variable year in the dataset, I would suggest:
summarize year, meanonly
local byear=r(min)
