Do you know where your variables are?

It makes great sense that a program with fewer values to consider would have fewer bugs. Are you talking about two different programs where one has fewer variables by its nature, or are you talking about removing variables consciously from existing programs?

The complicated data structures you mention I've always found handy for decreasing the overall number of variables, BTW. Instead of having a lot of related but disconnected variables that need to be passed around, I can have one data structure that describes a bunch of details about the current topic. I can then delete, alter, pass, and return the one data structure.

Let's look at a typical first-year programming class assignment. I think most of us have done a very simple payroll program. Just the function call illustrates the point:

figure_pay ( $name, $emp_id, $rate, $hours, $gets_overtime, $hours_without_ot, $ot_multi );
figure_pay ( \%employee );
So all other things being equal, I'd say you're definitely on to something. I think perhaps it's balanced against other issues, though, and shouldn't necessarily be a singular goal.

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).
