Print &

meechl has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks,

I would simply like to print out the character "&". All my attempts thus far have been futile, including use of "\&" or ascii codes. Thanks for the help!

Edit: Thanks for the replies! I am running perl on the command line and printing to a file. Here is the code for the out file generation and print statement:

 
my $outFile = $outbase . "_temp_stems_RNAcofold.txt";
open(OUT, ">$outFile") or die "Could not open $outFile.\n";
print OUT ">$name\t$compName\n$seq" . "&" . "$compSeq\n";

Edit 2: Wow, I'm an idiot. Was looking at the wrong output.

I have to assume you're printing to HTML. You want `&` if so. :P See also: HTML::Entities.	[reply] [d/l]

`print '&';` [download] works for me. What exactly are you doing and what error do you get?	[reply] [d/l]

An alternative to Your Mother's proposal: If you are using the CGI module, use "escapeHTML". `>perl -MCGI -E "say CGI::escapeHTML('&')" &` [download] This is not an optical illusion, it just looks like one.	[reply] [d/l]

You need to post runnable code that you've tried. This works for me: `use warnings; use strict; print "here is an ampersand ... & ...\n"; __END__ here is an ampersand ... & ...` [download]	[reply] [d/l]
