Generate age variable in a loop

[Agustina Queijo]

Hi!

I'm working building an anual dataframe, as the result of appending the respective monthly dataframe. At first, I build the first year with its respectiva variables and then I generate a loop for the next ones.
When I am generating the age variable it returns me an error because the td() command doesn't recognize the variable `anio' in that loop.

Here is an example of how I build it up without the loop:
g edad_012021=int((td(01jan2021)-fecha_nac)/365)

And there is the way I am coding into the loop (without other steps to prepare the dataframe):

forvalues anio=2012(1)2020 {
use "$datoscotiz\\`anio'_1_universo.dta", clear
g anio=`anio'
g mescargo=1
forvalues mescargo=2(1)12 {
append using "$datoscotiz\\`anio'_`mescargo'_universo.dta"
replace anio=`anio' if anio==.
replace mescargo=`mescargo' if mes==.
}
g edad_01`anio'=int((td(01jan`anio')-fecha_nac)/365)
}

I don't know if there is a problem with my code or maybe I should use another command.

Wish u can help me!

Thank's a lot for u all!

Please, let me know if you need a bit more information to understand the matter.

Thanks again!!

I don't think there should be a problem with the command recognising the macro anio at that point. Perhaps there is some other problem? Could you copy the contents of the Results window / log file so we can see the exact error?
