Thanks, I didn't know that "0" was documented to be "false" in a string context. Every other string should be "true".

That's just as weird as the "0 but true" situation. I don't know where that is documented and I've only seen it VERY, VERY rarely. Yes, it has to be spelled exactly like that and in the proper case.

I'm building a new main computer and started using a wimpy laptop to investigate some other problem and installed 5.22 (12 levels since 5.10) and I thought something had broken, but the only thing that "broke" were my eyeballs in conjunction with the font being used.

"0E0" is a documented part of the DBI, although lots of folks aren't aware of that. When you do an SQL UPDATE,SELECT or whatever, it is returned to say that the statement "worked", but it didn't do anything (0 rows affected). Its been a couple of years since I mucked with the DBI, but I've seen code that counts upon "0E0" quite a few times. When I do it, I put in a comment to explain what's going on, otherwise this fine point is obscure.

There are a lot of fine points and nuances with Perl. I will never know them all.

Title:
Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":


  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
