What is the difference between $dxyabc and ${dxyabc} in Perl?

Question

What is the difference between definition of string $dxyabc and string ${dxyabc} in Perl?

Answer 1

Well, it depends on the context. For example,

$foo = "$dxyabcdef";
$bar = "${dxyabc}def";

$foo will have the value of $dxyabcdef instead of $dxyabc appended with def, this is the value of $bar.

Otherwise, as far as I know, they are the same.
