I have alot of conditions in a function and would like to know if it can be shortened and made more efficient with the help of Perl experts. The script works on my NT but want to see if it can be shortened and look any better? 
use strict;
use warnings;
my $macf = 0;
my $syman = 0;
#intialize all the other variables etc...

#start of mainfunction here
sub mainfunction();
{
    if(($macf == 0) && ($syman == 0))
    {
        if(($mac eq $oldMac) && ($sym eq $oldSym))
        {
            print "no changes\n";
        }
        elsif(($mac ne $oldMac) && ($sym ne $oldSym))
        {
             print "section C UPDATE\n";
        }
        elsif($mac ne $oldMac)
        {
             print "section B UPDATE\n";
        }
        elsif($sym ne $oldSym)
        {
             print "SEction E updated\n";
         }
     }
     elsif(($macf == 0) && ($syman != 0))
     {
         if($mac ne $oldMac)
        {
            print "MacSEction updated\n";
        }
        else
        {
            print "no changes to mac\n";
        }
    }
    elsif(($macf != 0) && ($syman == 0))
    {
        if($sym ne $oldSym)
        {
            print "syman update\n";
        }
        else
        {
            print "no changes to syman\n";
        }
    }    
}
#end of main function

#start of condition checks to call correct function
if(($syman == 0) && ($macf == 0))
{
    myfunc1();
    myfunc2();
    mainfunction();
}
elsif(($syman == 0) && ($macf != 0))
{
    myfunc1();
    mainfunction();
}
elsif(($macf == 0) && ($syman != 0))
{
    myfunc2();
    mainfunction();
}
