Inputting a scalar in a new dataset

[Hossein Jebeli]

I would like to make a dataset by inserting the pre-defined scalar values.

Suppose I have scalar s as follows:

scalar s=3

When I make the following dataset, Stata can not read the numerical value of s.

input str2 coef b
"post" s
"tax" 2
end

Is there a way to input 3 as the value of s in this dataset?

Thanks
