First the code:

print "Question #1: Who is buried in Grant's tomb?\n\n";
print "A. Grant\n";
print    "B. Yoda\n";
print    "C. Liberace\n";
print    "D. None of the above.\n\n\n\n";
print "The answer is: ";

chomp($reply = <STDIN>);

#Following loop to test for a-d answers, courtesy of PerlMonks.org.
#This works but will not accept any answer without going thru this
#code block once

print "\nPick a letter between a and d.\n";
chomp(my $reply = <STDIN>);
while ($reply !~ /^[a-d]$/i) {
    print "\nPick a letter between a and d -- or else!\n";
    chomp($reply = <STDIN>);
}

If you've read the comments, you know what I can't fix. The code that I got here at Perlmonks does the job, but no response to the question will be accepted until that "while" loop runs once. When I asked for help a couple of weeks ago, I didn't include the code that showed the question. Maybe that would have made a difference. So, the question now is: How can I make sure that the answer to the question shown in the code is in the range a-d without showing the warning "Pick a letter between a and d" when the answer falls in the proper range?
