That's part of the "magic" of this variable. Explicit looping is not required.
http://perl.apache.org/embperl/pod/doc/Embperl.-page-3-.htm#sect_8 ############################################################################# Embperl can generate dynamic tables (one- or two-dimensional). You only need to specify one row or column. Embperl generates as many rows or columns as necessary. This is done by using the magic variables $row, $col, and $cnt. If you don't use $row/$col/$cnt within a table, Embperl does nothing and simply passes the table through. Embperl checks if any of $row, $col, or $cnt is used. Embperl repeats all text between <table> and </table>, as long as the expressions in which $row or $cnt occurs are defined. Embperl repeats all text between <tr> and </tr>, as long as the expressions in which $col or $cnt occurs are defined. See also $tabmode (below) for end-of-table criteria. Examples: (see eg/x/table.htm for more examples) [- @k = keys %ENV -] <TABLE> <TR> <TD>[+ $i=$row +]</TD> <TD>[+ $k[$row] +]</TD> <TD>[+ $ENV{$k[$i]} +]</TD> </TR> </TABLE> This will show all entries in array @k (which contains the keys from %ENV), so the whole environment is displayed (as in the while example), with the first column containing the zero-based index, the second containing the content of the variable name, and the third the environment variable's value. This could be used to display the result of a database query if you have the result in an array. You may provide as many columns as you need. It is also possible to call a 'fetch' subroutine in each table row. ############################################################################# On Wed, 26 Sep 2007, Perrin Harkins wrote: > On 9/26/07, Todd White <[EMAIL PROTECTED]> wrote: > > I'm wondering if anyone on this list would have any knowledge regarding > > the following Embperl question? > > I don't use Embperl, but it looks like you forgot to write all the > code to loop through your array and increment $cnt. > > - Perrin >
