Re^2: matching paragraphs

Thanks for your reply! How do I get the input in? The file is in the same folder and thus far I have only learnt how to work from standard input using a while loop e.g.
while ($line =<>); etc.
I cannot see where the input is coming from? Apologies for my lack of understanding!!!!

<> is an abreviation for < ARGV> and takes a filespec from the command line. < STDIN> reads from STDIO, `open FH, /dev/null or die "Can't open file\n"; while <FH> { #your code }` [download] This code sais: open the file /dev/null and give me a filehandle FH as a reference. Then read from the file referenced by FH and put that into $_. Stop reading at the end of the file.

< STDIN> reads from STDIO,
```
open FH, /dev/null or die "Can't open file\n";
while <FH> {
 #your code
}

This code sais: open the file /dev/null and give me a filehandle FH as a reference. Then read from the file referenced by FH and put that into $_. Stop reading at the end of the file.

That is wrong. You opened input.txt and created a filehandle INPUT. You are reading from input.txt.
