Hi,

Here's one method:

unab vlist: _all /* assign all variable names to local variable vlist */
foreach x of varlist `vlisit' {
capture confirm string variable `x'
if _rc~=0 {
/* do numeric variable processing here */
}
else {
/* do string processing here */
}
}

Hi,

I'm wondering if there's a way to loop through all my variables and
perform some action only on those that are numeric. Is there a way to
check for the type of the variable before doing something? Like

for each variable
if string, next
else do X
end for

Thanks!
