I would like store certain values to a list and drop if certain variable's value is equivalent to those values in list. Here is the code that I am working on:


Code:
local files : dir "C:\Users\E.YILMAZ\Desktop\www.thingiverse.com\Strata_Data\splitted_data" files "*.dta"
cd "C:\Users\splitted_data"
list = []
foreach file in `files' {
    cd "C:\Users\splitted_data"
    use  `file', clear
    for each x in list {
       drop if id == `x'
       }
    keep if  over_threshold == 1
    add_new_values_to_list
    save "new_`file'", replace
}
Could you please help me on this matter?
