Here's an example:

  use Win32::File qw(SetAttributes GetAttributes READONLY);

  my $pathToFile = "c:/somedir/somefile.txt";

  my $currentattrib = 0;
  GetAttributes($pathToFile, $currentattrib);

  SetAttributes($pathToFile, $currentattrib - READONLY);

Here's the solution:
#!/usr/bin/perl -w
use strict;
use Win32::File qw(GetAttributes SetAttributes READONLY NORMAL);

my $pathToFile = "d:\\test.txt";
my $currentattrib = 0;

#See attrib
GetAttributes($pathToFile, $currentattrib);
print "Current attrib: $currentattrib\n";

#Set to readonly
SetAttributes($pathToFile, READONLY);
GetAttributes($pathToFile, $currentattrib);
print "After setting to readonly: $currentattrib\n";

#Set to normal
SetAttributes($pathToFile, NORMAL);
GetAttributes($pathToFile, $currentattrib);
print "After setting to normal: $currentattrib\n";

"SetAttributes" is not exported by the Win32::File module
 "GetAttributes" is not exported by the Win32::File module

#!perl

$file = "/path/to/my_read_only_file.txt";

system("attrib -R $file");

use Win32::File qw(GetAttributes SetAttributes READONLY NORMAL);

to:

use Win32::File;
