Hi , My code is dependent on the output coming from a hardware , so couldnt share it earlier !! here's the simple form of my code 
#!/usr/bin/perl
use strict;
use warnings;
use File::Copy;    
my $value0 = 1;                        #change this to 0 and execute a
+nd back to one and execute
my $value1 ='true';
open (INFO, "> tmp");
print INFO "this is simple\n";
close (INFO);
open (FILE, ">> RESULT_LOG") ;
    print FILE " STATUS obtained : $value1\n";
if ($value0 == 1)
    {                                # If true then copies the informa
+tion to the RESULT_LOG
    copy("tmp","RESULT_LOG");}
else {
print FILE "Check keyword supplied\n";}
close(FILE);

You can run it once. It will create result_log and tmp files. Change the input my $value0 = 0; and run again ..Note: that it will append the result to the result_log. NOW change the my $value0 = 1; and run it again it will replace the result_log to have only recent output.So bottomline : After 1st true no matter how many false inputs it continues to append until it finds the true vondition again. So my question here is that , is it possible to stop replacing the old log and continue to append ? Note: I also found something strange. The line "this is simple" is appemded to the log file before the actual print.How is that possible ? -Thanks Ram
