x gets the assignment value of the string abc and the dereference of the variable $123, which if it is not set it would be undefined.
t gets the assignment value of the string xyz$. The `$' is not being interpreted by the shell as the dereference of a variable, since it exist as the last character. It is the equivalent of 'xyz$' or xyz\$

CheckDigits::M43_001(3pm) User Contributed Perl Documentation CheckDigits::M43_001(3pm)NAME
CheckDigits::M43_001 - compute check digits for Code-39
SYNOPSIS
use Algorithm::CheckDigits;
$c39 = CheckDigits('code_39');
if ($c39->is_valid('AB-123K')) {
# do something
}
$cn = $c39->complete('AB-123');
# $cn = 'AB-123K'
$cd = $c39->checkdigit('AB-123K');
# $cd = 'K'
$bn = $c39->basenumber('AB-123K');
# $bn = 'AB-123'
DESCRIPTION
ALGORITHM
1. After replacing all non numeric letters with their respective values, the sum of all numbers is computers
2. The checkdigit is the sum from step 1 taken modulo 43.
METHODS
is_valid($number)
Returns true only if $number consists solely of numbers and the last digit is a valid check digit according to the algorithm given
above.
Returns false otherwise,
complete($number)
The check digit for $number is computed and concatenated to the end of $number.
Returns the complete number with check digit or '' if $number does not consist solely of digits and spaces.
basenumber($number)
Returns the basenumber of $number if $number has a valid check digit.
Return '' otherwise.
checkdigit($number)
Returns the checkdigit of $number if $number has a valid check digit.
Return '' otherwise.
EXPORT
None by default.
