Going by the spelling error "bananaswiithapples.gif", I assume that you typed the sample in by hand rather than C&Ping from the real data. At least I hope you did because your records are inconsistant.

In the first record, the third field is wrapped at 8 chars. In the second record, the first two lines of that third field are wrapped at 8 chars and the last line at 9. In the third record, the first two lines of the third field are wrapped at 9 and the last line extends to 10.

There are similar inconsistacies in the wrapping of the second field/first record. I've adjusted the data to fit my assumption and I apologies if it is wrong.

This determines the output formatting by finding the maximum width of each field. It assumes that you have enough memory to accumulate all the records in memory. Otherwise it would be necessary to do two passes through the file:

#! perl -slw
use strict;

## The A template takes care of trailing spaces
my $inTempl = 'A8 x1 A9 x1 A8 A*';

my @headers = split ' ', <DATA>; ## Are these headers used?

my( @output, $accum );

while( my $line = <DATA> ) {
    chomp $line;
    my @bits = unpack $inTempl, $line;
    s[^\s*][]g for @bits; ## Trim leading spaces

    if( $line =~ m[^\S] ) { ## Start of a new record.
        ## Add to the list
        push @output, $accum if $accum;

        ## Start a new accumulation
        $accum = \@bits;
    }
    else {
        ## Append to the accumulators
        $accum->[ $_ ] .= $bits[ $_ ] for 0 .. $#bits;
    }
}
push @output, $accum; ## Don't forget the last record.

## Determine the output field widths
my @w = ( 0 ) x 4;
for my $ref ( @output ) {
    for my $i ( 0 .. 3 ) {
        my $len = length( $ref->[ $i ]||'' );
        $w[ $i ] = $len if $w[ $i ] < $len;
    }
}

## Build an output template with a extra space between fields
my $outTempl = join ' ', map 'A' . ($_+1), @w;

## And output
print pack $outTempl, @$_ for @output;
