Hi All,

      I have to extract few lines from 16MB file. I wrote a funcion for this purpose.

      The starting line looks like this "*|NET min_msb_led[0] 0.0103148PF" and the last line to be extracted is "blank line".

      I enter the "min_msb_led[0]" from key board, function returned "/^\*\|NET\smin_msb_led\0\/". It looks ok for me.

      Here is some stuff from my main program. 

      

		. 
		.
		.

$net_extract = name_modify($net);
		. 
		.
		.


ABC: while (<IN1>)

  {
  #print "entered into while loop\n";
      if ($_ =~ $net_extract) 
        {
         $count = 1;
         print "hello\n";
        }
		.
		.
		.
      Its entering into "while" loop but, "if" condition is not satisfied. Can any body tell me what is going wrong with this code. I can use array to read the line and compare with the input, but this is taking lot of time to execute the code.
