Basically i am trying to read a hexadecimal string such as the below mentioned 

0x401d50  
0x360aa7c030  
0x405dc2  
0x405dc9  
0x405dd0  
0x405dd5  
0x405dd8  
0x401bb0

compute the length of the same in bytes and compare to see if its lesser than 32 bytes(which is the size of a register that is going to hold all these addresses, which i am referring to as buffer) and if the comparison satisfies then i keep loading the instrutions until the register is full i.e unti lit reaches 32 bytes. Once it does i call it a miss . 

#! user/bin/perl

#use strict;
#use warnings;

$length_buffer= 0x100;
$base= 0;
$base_end= ($base+ $length_buffer-1);



open(FILE1," < output_log.txt") or die "can't read the file";         
+  

while(<FILE1>) {
    
    $inst_addr= $_;
    
    
    if($inst_addr) {
        
        use bytes;                                                    
+  
          $len_ofinstr=length( $inst_addr);                           
+     
          print " Length in bytes: ", $len_ofinstr, "\n";             
+     

    
    if($len_ofinstr >= $base && $len_ofinstr <=$base_end) {
        
        
        print FILE2 $hit. "\n";
        
        print " The inst fits in the buffer->hit, \n";
        $len_ofinstr+=$len_ofinstr;
        print "Total number of bytes in the buffer=", $len_ofinstr, "\
+n";
        
        $count_hit=$count_hit+1;
        print " Number of hits in the buffer= $count_hit", "\n";
        print FILE2 "number of hits in buffer". $count_hit. "\n";
    }
}
    else{
        
        if($len_inst == $length_buffer) {
            
            print " it can not hold anymore, \n";
            $base= $instr_addr & 0xffffffe0;
        }
    }
}

The snippet of the code is pasted above, the problem i am facing with the above pasted code is that, when $length_buffer= 0x100 (equivalent of the number 256 but not euvalent of 256 bits or 32 bytes) so the comparison is not really making any sense. Could anyone suggest how to fix this issue? thanks
