st: Re: Appending several files

[Jens Lauritsen <jl@epidata.dk>]

A simple technique can be  useful to "trick" Stata to behave like a 
dataset exists:
* create an empty dataset with one observation and one variable:
set obs 1
gen articifialvar = 1

* now you can do anything where Stata expects an open data set to be 
present, e.g. from
* the current discussion:
qui fs *
foreach f in `r(files)' {
append using `f'
}

* following appending all the files the first imaginary observation and 
variable can be dropped:
drop artificialvar
drop in 1
