[Trisquel-users] Need help to solve a loop issue in awk

[freelove]

I got a problem when I tried to use loop in awk

The input file is
I|A;B;C|a;b;c|1;2;3
II|D;E;F|d;e;f|4;5;6
III|G;H;I|g;h;i|7;8;9


The working awk script is

awk 'BEGIN{FS="|"}
{
    printf("%s ", $1);

    split($2, arr, ";");
    printf("%s ", arr[2]);

    split($3, arr, ";");
    printf("%s ", arr[2]);

    split($4, arr, ";");
    printf("%s ", arr[2]);

    printf("\n");
}' inputfile


But the following script does not work:

awk 'BEGIN{FS="|"}
{
    printf("%s ", $1);

    for (i = 1; i
