Generating and ordering a variable simultaneously

问题

I would like to avoid re-ordering the data to place the generated variable in the first column:

sysuse auto, clear
gen random = runiform()
order random

Is it possible to generate a variable and at the same time order it?

The idea is to be able to directly observe the generated variable when I browse the data in the editor, which is not easy when I have several variables.

回答1:

You can use the before() option:

sysuse auto, clear
generate random = runiform(), before(make)

You can also further automate this process as follows:

unab var : *
gettoken var : var

generate random = runiform(), before(`var')
