Hi guys,

Thanks for the input - both piece of code (from both monks)worked! Now I know to ditch my books and come here for enlightenment. But its not just the number of words I'm after, I need to have the file content in memory to parse and extract all proper names (i.e 2 or more consecutive words)from it.

I guess I'll have to go the sysread way. 

 
  my $buffer ;
        while (sysread TEXT, $buffer, $buffer_size) {
      ## This will use tr to count fast for you:
           $words += ($buffer =~ tr/ +\n+,://) ;
      }

I need to store $buffer in an array and then process it word by word. Is there any efficient way of doing that?

My entire code (if I dare show :)) looked something like this before: 

$fname =  "haystack.test";
open(TEXT, "<$fname")|| die "could not open file: $fname\n";

while (<TEXT>) { $txt .= $_; }

@words = split (/[ +\n+\,\:]/, $txt);
$len = @words;
print "LEN = $len\n";
close (TEXT);


$i =0;
while( $i< $len)
{
  my $flag2 = 1; 
  my $sptr = my $eptr = $words[$i];

     if($sptr =~ /^[A-Z][a-z]+/ )
    { 
    $eptr = $words[$i+1] ;
    
    if($eptr =~ /^[A-Z][a-z]*/ && $i< $len)
     {
     
     $i++;

     $sptr = $words[$i];
     $eptr =  $words[$i+1] ;    
     $flag2 = 0;
     
     while($eptr =~ /^[A-Z][a-z]*/ && $i < $len)
     {
    
     $i++;
     #print "I =$i\n";
     $sptr =  $words[$i] ;    
     $eptr =  $words[$i+1] ;    
     }
     if (flag2 ne 1)
     { print"\n";}
     }
    else
    {$i++;

    }
    else
    { $i++;}
   
   }

print"\n";

So do you think i'll be alright loading all the words in an array? Or is there a better way?

Thanks
