gawk: Can't print array in END block 2

[sqwawk]

I am new to awk and have created a very simple script. It should read file lines into an array and print all lines in the END block. But when I test it nothing prints except the counter value:

1:: (should be something here ...)
2::
3::
4::
...

Could someone please tell me what I am doing wrong? It's probably something simple, but its making me crazy!

BEGIN {
	FS="*"
	RS="\r"
	counter=1
}
{
	arr[$counter] = $0
	counter = counter + 1
	#print arr[$NR] 
}
END {
  for (x = 1; x < counter; x++) {
    print x "::" arr[1]
  }	
}

print x "::" arr[[!]x[/!]]

Hope This Helps, PH.

Thanks for the reply.

Sorry that was a copy/paste error. I tried so many things. When arr[x] did not work, I tried using a hard coded index [1] to see if it changed the results and posted that by accident.

What finally worked was changing how and where I incremented the counter value. I changed this

    arr[$counter] = $0
    counter = counter + 1

to this

    arr[counter++] = $0

But I don't understand why the one works and the other does not. From what I understand they both do the same thing. Can anyone explain the difference to me?

$counter is the value of the field number counter, not the value of counter.

well, the problem is in awk u don't need to add $ in front of the variable, so u just need to change ur old script to :

arr[counter] = $0

that should be works
cheers ;-)

$counter is the value of the field number counter, not the value of counter.

@PHV - Oh, so it has a special meaning and is not actually the value of my variable as I was thinking? Well that would explain why it didn't work. Thanks!

@gnsxhj,

Thanks for the response. Yes, that was one of the things I tried. But it didn't work so long as I was using a variable named "counter". Works perfectly with a variable name like "x" though
