Re^2: Check for next array element.

Couldn't that also be written as

   $data->{'IS_LAST'} = 0;
   for ( my $i = 0; $i < @list; $i++ ) {
      # DO STUFF
      $data->{'IS_LAST'} = 1 if $i == $#list;
   }

Too easy to make off-by-one mistakes that way. Use `for my $i ( 0 .. $#list ) { ... }` instead, unless you have speficic reason to use `for(;;)`. (I have never had such an occasion, but maybe you will.) Makeshifts last the longest.	[reply] [d/l] [select]

Sure, but then in the "DO STUFF" section you have to work with `$list[$i]` instead of `$_`. What are we, animals?! `:-)`	[reply] [d/l] [select]


Problems? Is your data what you think it is?
