hi,
can somebody explain me this?
probably i am overlooking something but i dont know what
why is not printed "7 9 11" instead of this?

$ echo "" | awk '{for(i=1;i<=3;i++){j=7;a=j;j=j+2;}   print a[1],a[2],a[3]; }'
7 7 7

thanks

You set j=7 at the start of each loop iteration. You should set it before the loop.

$ echo "" | awk '{j=7; for(i=1;i<=3;i++){a=j;j=j+2;}   print a[1],a[2],a[3]; }'
7 9 11
