thanks, I found that there is a bug. The curly braces don't make any
difference in fact ...
foreach ($fred as $fred1) foreach ($fred as $fred2) echo "$fred1 :
$fred2<br>";
is okay (but still doesn't work) although I have noticed that you seem to
need to code-block single statements in if ... else constructs
i.e
if (1==1) echo("fred") else echo("bill"):
should work but doesn't.
Another bug?.
