Hi again,

sprintf -- essential tool for avoiding hackery with interpolation and escaping.

push(@data, [
    1234565,
    'Prototype',
    sprintf('Number in address is %s. Please, Please check your record
+s.', $number),
]);
[download]

(I advise always using parens with push and any function that will slurp up whatever's left on the line as args...)

Hope this helps!
