I'd forgotten about this. Thanks for the plug.

I think this predates SSC. Either way, it is probably not on SSC because

I just posted it there and did not bother to write a help file. Stuff like that never makes the grade to SSC and thus to -njc_stuff- on SSC.

Twelve years on, that's still my inclination.

A very good reason for that, as already pointed out, is that -defv- already exists to do the job.

A key detail for Kit's program is that -gettoken- should parse on equals signs as well.

Also, what happens if people write -mygen double lprice = log(price)-?

Yes - Nick Cox wrote -labgen.ado- which does excactly that. FOr some reason this is not on SSC. Perhaps Nick could make it avaliable. *! version 1.0.1 7/17/1996 program define labgen version 4.0 parse "`*'", parse(" =") if "`2'"=="=" { local var `1' mac shift 2 } else if "`3'"=="=" { local type `1' mac shift local var `1' mac shift 2 } else { error 198 } gen `type' `var' = `*' label var `var' "`*'" end

Not to my knowledge.

Probably the best way of documenting this is to use variable -notes-. Try this:

program mygen

qui gen `0'

gettoken name rest: 0

note `name': `0'

end

mygen lprice = log(price)

mygen gpm = 1/mpg

I wonder if you could help me with an Stata issue.Is it possible for stata to automatically label a new variable with the formula used in "gen"? ex: gen y = x+1 automatically yielding label variable y with "gen y = x+1"
