Dear all,
I have a problem when I append a list of files (named from v2.dta to v66.dta)
to the current dataset (v1.dta). Incidentally, all these files contain the
same variables, in the same order.
The command I use is the following:
**************************************
use c:\data\v1
forvalues i = 2(1)66 {
append using "c:\data\v`i'"
}
**************************************
when I look at the data in the resulting dataset many observations are
duplicated, as Stata had appended twice the same file. I have also tried to
use the alternatives:
**************************************
foreach file in v2.dta v3dta v4.dta��.v66.dta {
append using "`file'"
}
**************************************
and:
**************************************
local i = 1
use c:\data\v`i', clear
while `i'<=66 {
append using c:\data\v`i'
local i = `i' + 1
}
**************************************
but I always get the same strange result.
Thank you in advance for any suggestions
