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

It's not a limitation of Perl at all. At least for some values of “limitation”.

The cause of this is that there is no two dimensional array in Perl. You are constructing a representation of such by using an array of arrays, but a one-dimensional array of one-dimensional arrays is not the same as a two dimensional array. There are fewer constraints on such a data structure (the subarrays need not be uniform in length) but in turn, it also loses some expressiveness since you only address one array at a time. You can still represent all operations possible on a two-dimesional array using an array of arrays, but it does require looping.

To do what the OP wants to do, it would also have to be possible to say @{ \@a, \@b, \@c }[ 3 ], which it is not.

Makeshifts last the longest.

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.
