No problem with awk or gawk:

$ for ((i = 0; i < 10; ++i))
    printf "%d %d %d %d\n" $((i+1)) $((i+2)) $((i+3)) $((i+4))
  done > test.txt
$ awk '{print($1, $2, $3)}' test.txt
1 2 3
2 3 4
3 4 5
4 5 6
5 6 7
6 7 8
7 8 9
8 9 10
9 10 11
10 11 12

So the issue appears to be with your command line, script, or input data file:
please show the command line used to execute the script, attach the complete awk
script, and input data file for diagnosis, or selections of the latter piped
through or output using cat -A to show control characters.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
