kiat has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,

I'm curious why the statement below prints the characters 'foo':

print v102.111.111;

Please enlighten me and thanks in anticipation :)

`v1.2.3` is equivalent to `chr(1).chr(2).chr(3)` by design. By doing this, `v1.11 gt v1.2` is true. If you want to print out a vstring, use (s)printf's %v specifier. However, note that this will be changing in Perl 5.8--vstrings will become objects (I think the class will be `UNIVERSAL::version`). =cut --Brent Dax There is no sig.	[reply] [d/l] [select]

Thanks for responding! The example comes from "Programming Perl 3rd Edition" (Larry Wall et al), p. 67.	[reply]

A better question is: "how did you come up with your example"? It seems very coincidental that your example gives "foo"...;)	[reply]
