Slight error with my perl script that I could use some help on

So I have a perl script that prompts the user to enter either q or Q to exit the program or c to continue said program. If the user inputs anything other than those three keys they will be prompted again and again for an appropriate input. My script works for the most part except for one small oddity. Here's an example- if the user inputs a, they will be prompted again. They input a again, they are prompted once more. They input q and the program exits. Works fine right? I run my script again and I change my inputs a little. This time I input a first, the user is prompted again. Now I input q, but the program doesn't exit, it prompts me yet again. If I input q now, it will exit. This oddity also occurs if it's Q or c as well instead of q. This is the oddity I want to fix, can anyone help? Here is the bulk of my code that deals with this small problem-

Code:

print "Welcome to an interactive Perl program. Enter either q or Q to terminate the program or c to continue. Enter your key now: ";
my $input;
$input = <STDIN>;
chomp $input;
if (($input ne "q") && ($input ne "Q") && ($input ne "c"))
        {
                print "Welcome to an interactive Perl program. Enter either q or Q to terminate the program or c to continue. Enter your key now: ";
                $input = <STDIN>;
                chomp $input;
        }
elsif (($input eq "q") || ($input eq "Q"))
        {
                exit;
        }
else
        {

the parts after else aren't important, as I've tested them and they work fine. It's only the small oddity that I described above that I need assistance with

asp-perl

ASP-PERL(1p)						User Contributed Perl Documentation					      ASP-PERL(1p)

NAME

       asp-perl - Apache::ASP CGI and command line script processor

SYNOPSIS

       asp-perl [-hsdb] [-f asp.conf] [-o directory] file1 @arguments file2 @arguments ...

	   -h  Help you are getting now!
	   -f  Specify an alternate configuration file other than ./asp.conf
	   -s  Setup $Session and $Application state for script.
	   -d  Set to debug code upon errors.
	   -b  Only return body of document, no headers.
	   -o  Output directory, writes to files there instead of STDOUT
	   -p  GlobalPackage config, what perl package are the scripts compiled in.

DESCRIPTION

       This program will run Apache::ASP scripts from the command line.  Each file that is specified will be run, and the $Request->QueryString()
       and $Request->Form() data will be initialized by the @arguments following the script file name.

       The @arguments will be written as space separated words, and will be initialized as an associate array where %arguments = @arguments.  As
       an example:

	asp-perl file.asp key1 value1 key2 value2

       would be similar to calling the file.asp in a web environment like

	/file.asp?key1=value1&key2=value2

       The asp.conf script will be read from the current directory for parameters that would be set with PerlSetVar normally under mod_perl.  For
       more information on how to configure the asp.conf file, please see < http://www.apache-asp.org/cgi.html >
