To expand on that:
**********
*clear mem
clear*
ma drop _all
*create fancy new dataset
sysuse auto, clear
drop in -30/l
save autonew, replace
*determine variables amenable to this analysis and store them and their
levels in -local-s
sysuse auto, clear
ds, has(type numeric)
loc variables `r(varlist)'
qui foreach var of loc variables{
levelsof `var', loc(levof`var')
}
*do whatever you want in second dataset
u autonew, clear
foreach var of loc variables{
di _n(2) in red "Currently at variable `var'" _n(2) "Levels of `var':" _n
foreach lev of loc levof`var'{
<put your analysis in terms of `lev' in here>
}
}

Subject: st: looping with vars across file
Hi,
I have two files, file 1 and file 2. I want to use each var (one by
one) from file 1 to run a loop in file 2.
Eg:
File one:
var1 var2....varn
101 99 .
76 104 .
89 107 .
I want to run a loop in file two that takes each value for vars1-varn
in file 1 and loops over it: So for var1 of file1, I want to run the
following loop in file2:
foreach i in `i' 101 76 89 {
......
}
and so on for each var of file 1.
Is there a way to do that?
