in thread Insert Text which is Read from the Line Above

Hi NetWallah.

That is absolutely amazing.

As I am part of the below average person group you will have to help me with one further question.

I managed to capture the output through running the command on Explorer^2's DOS Command line option.

I pasted the output into a text file and all my checks so far on your output after running the code on a 2600 line input file have found the output to be 100% correct.

However, I need to capture the output in a more easy way.

How do I insert this code into a .pl file? Do I need 'if ($line =~ ........' etc.

If you can give me some idea on that it will help me so much for this particular program and many more in the future.

Many, many, many thanks.

      Hi poj.

      Thank you for your assistance.

      You guys/gals are advanced here.

      I replaced the  my $infile = $ARGV[0]; with  my $infile = C:\Users\... \abc.txt;

      Similar with the output file.

      I knew it was not right to do this but I did not know what else to do.

      How do I get my input file read in and the output into the output file?

      Again, thank you very much for the code and assistance.
