IIUC you meanwhile have your script running, and probably code similar
to

    BEGIN { print_file_words("data.txt"); }

    function print_file_words(file) {
        while (getline <file >0)
            arr[$1] = $0
        PROCINFO["sorted_in"] = "@ind_num_asc"
        for (i in arr) {
            split (arr[i], arr2)
            printf "%s ", arr2[2]
        }
        printf "\n"
    }

I suggest to add the '>0' test to your code, and also print a final
"\n" so that your command line prompt doesn't overwrite your output.
Note also that printf (like print) is a command, no function. Adding
local variable declarations is also sensible to not get problems if
you operate your code in other source code contexts.
