in thread Out of memory error!!!

I have to collect data from all the lines in the input file and then print it to the XML file.

Actually the input file is huge,..but now for testing we are using a input file with 30 lines for which we are getting the error.

    ... while (defined(my $line2 = $INFO)) { ...

    ... you need to use the diamond operator to read from a file line by line:

    ... while (defined(my $line2 = <$INFO>)) { ...

    First of all. 30 lines mean nothing when you don't know how long the lines are. We never talked about that. Probably you have a unusual encoding where the line ending is not the same as with unix. Do you really have LF (0x0a) for a line ending?

    Is there some weird preallocation which is unrelated to the count of line which blows your memory resources?

    Can't you give us a little complete running example showing us the error message? Otherwise I don't know how to help you any further.

      Hi

      I tried to run the program and printed the line and got the ouput as below. Its working fine till getting values from C1 line and then when it comes to C2 it is throwing error. I'm assigning some array using substr command in my script.

      $a=0;

      $b=0;

      i.e

      $Var20$a$b = trim(substr($line2,11,15));

      $a++;

      $b++;

      something like that..

      Output:

      A0XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXx

      A1XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX XXXXXXXXXXXXXXX

      A2

      A3

      A4

      A5

      A6

      A7

      A8

      A9

      AA

      C1

      C2XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

      Out of memory!

      I couldnot get what u meant by LF().

      There are some variable assignment in the beginning of the script as well. The file size which Im processing is 5kb only :-(

      Thanks & Regards,

      Sathya V.
