It doesn't matter to Perl if you store alphanumerics or numbers or both in
scalar. When you want to perform a numeric function on the scalar, Perl
treats the data in it as numeric. When you want to perform an alphanumeric
on it, it treats the data as alphanumerics.
e.g
$data = "one";
$new = "$da

hELLO,
$@ is a system variable that return error messages. If our statement
executed by the eval function (eval 'exec perl $0 -S ${1+"$@"}')
contains an error, or an error occurs during the execution of the
statement, the error message is stored in $@.
I.e:
eval ("This is not a perl statement")
