Hello, I have written a code in Perl. I wanted to know how do I refer to the command line arguments as my input/output files. My code: 
#!/usr/intel/bin/perl
use warnings;
use strict;

my $find_flag;                            #using a flag variable

while ( <> ){
  if (/^\S/){                             #match a line that start wit
+h no space
    if (/^\w+clk\[\d+\]/){                #match requested headline
      $find_flag = 0;
    }
    else{
      $find_flag = 1;
    }
  }
  next if $find_flag and /\s+QUALIFIED_CLOCK/;     #skips the line req
+uested
  print qq{$_};                                    #printing ordinary 
+line
}

The command line should be of the form: CODENAME INPUTFILE OUTPUTFILE STRING so my code will edit INPUTFILE, print the result to OUTPUTFILE and replace "QUALIFIED_CLOCK" with STRING. Thanks!
