Hi everybody
I wanna store some values that r in a .txt file in some arrays
for example I have:

32782   28
 32783   02
 32784   01
 32785   29
 32786   25
 32787   25
 32788   00
 32789   25
 32790   02
 32791   29
 32792   23
 32793   01
 32794   28

and I need to save the first column in X [i]and the second one in Y[j].
And how can I refer to this value for example print on screen?
Tnx in advance for your help

Just an example (to be adapted depending on your needs)

$ awk '{X[NR]=$1;Y[NR]=$2}END{print X[2]"\n"Y[10]}' input
32783
29

NR stand for Number of Record since the RS (Record Separator) is the newline character by default, NR here simply refer to the line number.

If you are talking shell array, try this. Syntax will vary from shell to shell, this one is bash (index starting at 0):

$ X=($(awk '{print $1}' file))
$ echo ${#X[@]}                            # element count
13
$ echo ${X[@]}                             # all elements
32782 32783 32784 32785 32786 32787 32788 32789 32790 32791 32792 32793 32794
$ Y=($(awk '{print $2}' file))
$ echo ${X[2]}, ${Y[2]}                    # third pair
32784, 01

Here is another example, saving $1 in array val

FNR == NR {
  />/ && idx[FNR] = ++i
  $2 || val = $1      # Store source location
  next
}

Thanks to all for solving my problem
