First of all, get rid of those backslashes. No need to put your string in
parens. You can do this:
print "Is your Terminal ANSI compliant?\nYes or No, (y) or (n)?\n"

The problem is that you are assigning an array to a scalar, which means
your array is put into a scalar context, which means the scalar will be
assigned number of elements in the array. Since you are only passing one
argument to the sub, you just need:
sub verifyInput {
my $vInput = shift;
...
}
If you have multiple arguments, you can do:
my ($vInput1, $vInput2) = @_;
or
my $vInput1 = shift;
my $vInput2 = shift;
