Hi.
I think the list is missing a post or two in this thread?

In this anchor:
<a href="move.pl?direction=NW&cx=5&cy=10&player=Lou;">
the separators in the href URL are ampersands, each one coded as the
character entity
&
which requires the semicolon as its terminator. The 'real' URL is
therefore:
move.pl?direction=NW&cx=5&cy=10&player=Lou;
which is still odd in that 'player' is 'Lou;', but that shouldn't be
a problem.

The brackets (), [], {} and <> all have special meanings in Perl. The
parentheses are generally used for prioritising, in the traditional
way. Braces are used in several different contexts, but in this case
(I imagine, without seeing it!) they are used to delimit a hash key:
$hash{'key'}
in the same way as square brackets are used to index an array.
Using parentheses here, as in:
$hash('key')
looks like a subroutine call, but is just a syntax error.

Rob
