( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I am working on this sort of thing now. The inability to directly modify structures under MLDBM is not so much of an issue as you might think. I'm very new to MLDBM, so take this with NaCl

My current idea is that one could prepare a subroutine that returns an array and use it like this...

# We want to change element 4 of array foo to '12' $MLDBMhash{foo} = &Revise_It($MLDBMhash{foo},'4','12'); sub &Revise_It { @somearray = @($_[0]); $somearry[$_[1]] = $_[2]; return @somearray; }

This is all off the top of my head. Obviously, under some conditions, you could easily have just an UpdateArray function that returned only success or failure. Depends on what you want to do. That method could quite possibly make the code more readable since at a glance anyone can see what array and which place are being updated with what value.

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.
