The following script works, reading from the DATA section:

#! /usr/bin/perl -C255

use strict;
use warnings;
use LWP::Simple;
use Encode 'decode';
use URL::Encode ':all';
use feature 'unicode_strings';
use utf8;
use open ':encoding(UTF-8)';

open INFIL, "<:encoding(UTF-8)", "temp.txt" or die; #This line generat
+es a warning.

#while (<INFIL>) {
while (<DATA>) {
    chomp;
    my $title = $_;
    $title =~ s/\/.*//;
    $title =~ s/\[by.*//;
    print "Title Searched: $title\n";
    $title = url_encode_utf8($title);
    my $html = getprint("https://clio.columbia.edu/catalog?q=$title&se
+arch_field=title_starts_with&f%5B-format%5D%5B%5D=Online&commit=Searc
+h") or die;
}

exit;

But, if I change it to read from a file, like so:

#! /usr/bin/perl -C255

use strict;
use warnings;
use LWP::Simple;
use Encode 'decode';
use URL::Encode ':all';
use feature 'unicode_strings';
use utf8;
use open ':encoding(UTF-8)';

open INFIL, "<:encoding(UTF-8)", "temp.txt" or die;

#while (<DATA>) { ###CHANGE HERE###
while (<INFIL>) {
    chomp;
    my $title = $_;
    $title =~ s/\/.*//;
    $title =~ s/\[by.*//;
    print "Title Searched: $title\n";
    $title = url_encode_utf8($title);
    my $html = getprint("https://clio.columbia.edu/catalog?q=$title&se
+arch_field=title_starts_with&f%5B-format%5D%5B%5D=Online&commit=Searc
+h") or die;
}

exit;

__DATA__

I get the error: 501 Protocol scheme 'https' is not supported (LWP::Protocol::https not installed) <URL:https://clio.columbia.edu/catalog?q=How+to+conduct+your+own+survey+&search_field=title_starts_with&f%5B-format%5D%5B%5D=Online&commit=Search>

The input file contains only a single line, the same as the DATA section.

I've tried this on both Strawberry Perl 5.24.1 and Cygwin Perl 5.22.3

All feedback appreciated.

Thanks, Michael
