Code:
#! /opt/third-party/bin/perl

use strict;

my ($header, $i, $headerSet, %fileHash, $content, $trailer);

open(FILE, "<", "inputfile") || die "Unable to open file 'inputfile' <$!>\n";

while ( <FILE> ) {
  if ( $headerSet != 1 && !/^ZZZZ/ ) {
    $header .= $_;
  }
  elsif ( /^ZZZZ/ ) {
    $headerSet = 1;
    $fileHash{$i++} = $content if( length($content) );
    $content = "";
    $content .= $_;
  }
  elsif ( /^BBBP/ ) {
    $trailer .= $_;
  }
  else {
    $content .= $_;
  }
}
$fileHash{$i++} = $content;

close(FILE);

$fileHash{"header"} = $header;
$fileHash{"trailer"} = $trailer;

for( my $x=0; $x<$i; $x++ ) {
  open(FILE, ">", $x);
    print FILE $fileHash{"header"};
    print FILE $fileHash{$x};
    print FILE $fileHash{"trailer"};
  close(FILE);
}

exit 0

NB: this only tested with your sample.
Code:
awk 'BEGIN{c=1}
     /^AAA.+nmon_aix53#/  {print > "file"c }
     /^ZZZZ/,/^BBBP.+ending vmstat -v#/{
        if ($0~/^BBBP/){c=c+1;print >"file"c;next}
	else {	print > "file"c}
     }  
' "file"

' "file"

I wonder how it worked actually.

This would not seperate the "ZZZZ" tags and footer will not be appended to the end.
Morever only first line from the header section would be appended.

Holy Smoke!

Ok, Matrixmadhan, Your solution worked like a charm!

The only bad thing is that I have spent many days on this ....
Tried sed, awk.
Tried to understand lex/yacc.
Stupid, stupid me ...

Thanks a lot!
