Re^5: Loop Array - If $var is something write values until $var is something else

Here's my take on what I think you are after, I have omitted the "(could be removed)" items. The code:-

use strict;
use warnings;

use feature qw{ say };

open my $dataFH, q{<}, \ <<__EOD__ or die $!;
JOB::HEREISASTRING
Something
StringA
StringB
StringC
StringD
Something Else
StringE
StringF
StringG
StringH
JOB::HEREISANOTHERSTRING
Something
StringI
StringJ
StringK
StringL
Something Else
StringM
StringN
StringO
StringP
__EOD__

chomp( my @cleared = <$dataFH> );
close $dataFH or die $!;

my $flag;
foreach my $item ( @cleared )
{
    if ( $item =~ m{^JOB} )
    {
        say $item;
        next;
    }
    elsif ( $item !~ m{^String} )
    {
        $flag = $item;
        next;
    }
    else
    {
        say qq{~~$flag~~$item};
    }
}

The output:-

JOB::HEREISASTRING
~~Something~~StringA
~~Something~~StringB
~~Something~~StringC
~~Something~~StringD
~~Something Else~~StringE
~~Something Else~~StringF
~~Something Else~~StringG
~~Something Else~~StringH
JOB::HEREISANOTHERSTRING
~~Something~~StringI
~~Something~~StringJ
~~Something~~StringK
~~Something~~StringL
~~Something Else~~StringM
~~Something Else~~StringN
~~Something Else~~StringO
~~Something Else~~StringP

I hope this is helpful.

`elsif ( $item !~ m{^String} ) { ... }` My interpretation is that the `StringA` etc. input items are supposed to represent any input strings at all rather than strings that all start with `'String'`. I think that only the `'JOB::...'`, `'Something'` and `'Something Else'` strings are supposed to be constants. Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
