Java substr() limitations in "AWK" program..!!!
Is there any limitation for the function substr()
Iam trying to assign some 11 digit number value to variable. And printing the variable. This is printing invalid values.

cur_val=substr($0,36,11);
printf "Current Value is: %d\n",cur_val

I tried till 9 digits length, it was working fine. If I select more than 10 digits problem occurs.

What could be the problem and what are the alternatives in awk script.

This would be helpful for all...

Thanks in advance / Lokiman

substr will return the substring of the string provided. I am not clear wether you want to use this function or the index function

It may be because of %d in printf, try %ld in printf
my be in ur unix version %d is having 9 digit limitation, but for me both %d and %ld is giving same result. Just try

that statement says get the substring starting from position 36. make sure your $0 has more positions than that.

Question $0 has 120 charecter length.
$0 has 120 charecter length.

I think this could be the limitation with the '%d'.
Are there any other reasons and alternatives?

Thanks
