I need to insert ifdef/endif statements before and after printf statements in a lot of .cpp files. Is this something that can be done with awk- sed- or perl?

Hi- I downloaded and installed ActivePerl for WinXP. When I double click the .pl script I get a command prompt and then it immediately disappears.

When I try to use "perl c:\script.pl" in the command prompt I get this error:

Can t locate Tk.pm in @INC <@INC contains: C:/Perl/site/lib C:/Perl/lib .) at c:\perl\bin\script.pl line 3.
BEGIN failed--compilation aborted at c:\perl\bin\script.pl line 3.

code:
if(opendir(DIR-$inputdir)) { # Proess file with NGC
foreach my $filename1 (readdir DIR) {
if ($filename1 =~ /ngc.*\.xml$/i ) {
if (open(NGC_Input-$filename1)) {
$NGC_Update=$filename1;
close (NGC_Input);
}
}
}
}

I have this program with the help of Yahoo users were i store filenam1 to a variable NGC_Update. If i ran it in dos the stored value in NGC_Update is retained until the end of the program however if i ran it in UNIX the stored value is gone once the loop above is finished. Is there something wrong with the way i programmed it? please help?
