Hi i have a script that should look like this-
###########################################################
Plan: the plan its accessing
Chapter: the chapter under that plan
Owner:Default owner (there can be multiple owners)
Platfrom: Default platform
Env : Default environemt

(milestone=1 , env= if its not the default env display the other env here)
#print files relevant to milestone 1 under that plan under that chapter
filename1
filename2
filename3
filename4
(milestone=2 , env= if its not the default env display the other env here)
filename5
filename6
filename7
(milestone=3 , env= if its not the default env display the other env here)
filename8
(milestone=4 , env= if its not the default env display the other env here)
filename9
filename10
filename11
filename12
filename13
filename14
#############################################################

but instead looks like

############################################################
Plan: the plan its accessing
Chapter: the chapter under that plan
Owner:Default owner (there can be multiple owners)
Platfrom: Default platform
Env : Default environemt

(milestone=1 , env= if its not the default env display the other env here)
#print files relevant to milestone 1 under that plan under that chapter
filename1
filename2
filename3
filename4

Plan: the plan its accessing
Chapter: the chapter under that plan
Owner:Default owner (there can be multiple owners)
Platfrom: Default platform
Env : Default environemt

(milestone=2 , env= if its not the default env display the other env here)
filename5
filename6
filename7

Plan: the plan its accessing
Chapter: the chapter under that plan
Owner:Default owner (there can be multiple owners)
Platfrom: Default platform
Env : Default environemt

(milestone=3 , env= if its not the default env display the other env here)
filename8

Plan: the plan its accessing
Chapter: the chapter under that plan
Owner:Default owner (there can be multiple owners)
Platfrom: Default platform
Env : Default environemt

(milestone=4 , env= if its not the default env display the other env here)
filename9
filename10
filename11
filename12
filename13
filename14
##############################################################

So the body of my code looks like this
##############################################################
my $flag = 0;
foreach $plan(@plan){
      foreach $chap(@chap){
            foreach $mlst (@milestone){
                  foreach $plt (@platform){
                  for (i=0;i<=200;i++ )
                  if (($some{$hash}{$of}{plan} eq $plan) && ($some{$hash}{$of}{chap} eq $chap)&&($some{$hash}{$of}{mlst} eq $mlst)&&($some{$hash}{$of}{plt} eq $plt))
{
if ($flag ==0){
print "Plan= $plan";
print "Chapter=$chap";
print "Owner=$owner"; #processed in a subroutine
print "Platform=$plt";
print "(Milestone = $mlst , env: $en)";
}
print "$some{$hash}{$of}{filename}";
$flag = 1;
} } }  } }...
###########################################################

Please help me fix it !!

If I understand what you're trying to do this may work:

foreach $plan(@plan){
	print "Plan= $plan";
	foreach $chap(@chap){
		print "Chapter=$chap";
		print "Owner=$owner"; #processed in a subroutine
		print "Platform=$plt";
            foreach $mlst (@milestone){
		print "(Milestone = $mlst , env: $en)";
                  foreach $plt (@platform){
			  for (i=0;i<=200;i++ )
			  if (($some{$hash}{$of}{plan} eq $plan) && ($some{$hash}{$of}{chap} eq $chap)&&($some{$hash}{$of}{mlst} eq $mlst)&&($some{$hash}{$of}{plt} eq $plt))
				print "$some{$hash}{$of}{filename}";
			}
		}
	}
}

I'm sorry but it does not work :(

It prints the header for all the iterations its going through. And i just want it printed once at the top for that particular values relevant to those elements in the loop.

I'm sorry it didn't work for you.  This might be worth a try.

foreach $plan(@plan){
	if (($some{$hash}{$of}{plan} eq $plan)	print "Plan= $plan";
	foreach $chap(@chap){
	if (($some{$hash}{$of}{plan} eq $plan) && ($some{$hash}{$of}{chap} eq $chap){
		print "Chapter=$chap";
		print "Owner=$owner"; #processed in a subroutine
		print "Platform=$plt";
		}
            foreach $mlst (@milestone){
		if (($some{$hash}{$of}{plan} eq $plan) && ($some{$hash}{$of}{chap} eq $chap)&&($some{$hash}{$of}{mlst} eq $mlst) print "(Milestone = $mlst , env: $en)";
                  foreach $plt (@platform){
			  for (i=0;i<=200;i++ )
			  if (($some{$hash}{$of}{plan} eq $plan) && ($some{$hash}{$of}{chap} eq $chap)&&($some{$hash}{$of}{mlst} eq $mlst)&&($some{$hash}{$of}{plt} eq $plt))
				print "$some{$hash}{$of}{filename}";
			}
		}
	}
}
