Re: $cnt doesn't work for me as advertised (fwd)

That's part of the "magic" of this variable.  Explicit looping is not
required.

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.
