Re: printing words without newlines?

I'm learning more AWK basics and wrote function to read file, sort,
print.  I use GNU AWK (gawk) and its sort but printing is harder to get
working than anything... separate lines work, but when I use printf() or
set ORS then use print (for words one line) all awk outputs (on FreeBSD
UNIX 14 and Slackware GNU/Linux 15) is a space (and not even newline
before shell prompt)... is this normal (and I made mistake?) or am I
approaching it wrong?  I recall BASIC prints new lines, but as I learned
basic C and some derivatives, I'm used to newlines only being
specified...

I think you forgot that arr2 is now an array => you have to iterate over
it as well.  There were also a few other coding errors, ie. not closing
the data.txt file; not declaring local vars in print_file_words:
 
--
$ cat test.awk BEGIN { print_file_words("data.txt") }
 
function print_file_words(file,  i,j) {
  ORS = " " PROCINFO["sorted_in"]="@ind_num_asc"
  while (getline <file >0)
    arr[$1] = $0
  close (file)
 
  for(i in arr) {
    split(arr[i],arr2)
for (j in arr2)
      print arr2[j]
  }
  ORS = "\n"
  print ""
}
 
$ gawk -f test.awk all are base belong to us your

My original works after rebooting after discussion in main thread (without
'Re') but thanks for instruction to close file, though I don't know you
need to pass in i--not used outside.  It's odd iterating over arr2 even
still prints all words (wrong order) because the way I used arr2 it only
ever had one number and one word--its point was to split out & get word,
then for the next i, it's split again onto arr2 which is erased/updated.
