Hi, This is my first post. I've encountered some Perl functionality that I can't find any documentation for and can be demonstrated by the following two command lines (I'm running on Linux and Perl v5.26.1):

perl -E 'printf "%s\n", chr 65'

This line prints the character 'A'. The following line also prints the character 'A'

perl -E 'printf "%s\n", v65'

It appears that v<number> is some kind of internal equivalent to chr(number) call, however, I can't find any search results in any of my perl books and Google searches. Can anyone shed some light on this?
