Thanks a ton for that quick reply... Indeed, as you mentioned, exec was the culprit (I am a n00b ;-) ). The code fragment, nonetheless is here (have commented out the exec) - Thanks again for your help and reply on the dot.: 
#!/usr/bin/perl

system "date";



#system 'ls -l $HOME |awk \'{ print $8 }\'';



#exec "date";



#print "$ENV{'PATH'}\n";

#$ENV{'PATH'} = "/home/athampan:$ENV{'PATH'}";

#print "$ENV{'PATH'}\n";





foreach $var (sort keys %ENV)  {

     print "$var => $ENV{$var}\n"

}
