Hi there
I have a text file that looks something like this 
filename =

without012.csv


pred =

   -0.0105
    0.0645
    0.1989
    0.0151
    0.0289
    0.0400
    0.5313


filename =

without013.csv


pred =

   -0.0080
    0.0663
    0.1911
    0.0075
    0.0288
    0.0302
    0.5234


filename =

without014.csv


pred =

   -0.0023
    0.0595
    0.2582
    0.0323
    0.0285
    0.0578
    0.5807

And so on. This text file was produced from 120 smaller .csv files, as you can probably guess from the names .. lol. What I need to do is to save each individual 'block' of numeric values .. for example 
-0.0023
    0.0595
    0.2582
    0.0323
    0.0285
    0.0578
    0.5807

Into separate files, with each file being saved according to the smaller files from which these results originate. So, for the example below 
filename =

without014.csv


pred =

   -0.0023
    0.0595
    0.2582
    0.0323
    0.0285
    0.0578
    0.5807

I would like to save the numeric block in a small file called without014.csv.
With this in mind I started writing a perl script as follows: 
#!/usr/bin/perl

@file = <>;

for($i = 0; $i < @file; $i+4)
{

    print "$file[$i]";
}

I was hoping that it would print out just the file names initially and then I was going to use the same technique for extracting the numeric block but all I am getting is blank lines when I run it (and yes, I'm checking that I am attempting to print off 'the right line' lol).
Anyway .. it's obvious that I am not getting very far .. so any suggestions/tips would be much appreciated.
