Just a quick note that technically this is not an error, but a warning.  It
does not affect the execution of the code at all.  Errors end the program,
warnings don't.  See perldiag.pod ("Various Perl diagnostics" under Help)
for (what should be) a complete list of all warnings and errors.  Also, you
can get more information with "use diagnostics":


#! perl -w
use diagnostics;
$holdingThing = 'Backup Folder';
__END__

# Name "main::holdingThing" used only once: possible typo.
File 'Bourque:Desktop Folder:Untitled1'; Line 3 # (#1)

    (W) Typographical errors often show up as unique variable names.
    If you had a good reason for having a unique name, then just mention
    it again somehow to suppress the message.  The use vars pragma is
    provided for just this purpose.
