$file is passed from the calling php file. index.php is by-hand
and so on.
Because of my shoulder/typing woes, it was great that I got clued in
above by Brad's thought that perhaos there were mis-matched "<?"
and "?>" tags. A simply recursive grepping found out that it some
places I had "<?" <cr> instead of "<?php"> <cr>. Adding the "php"
Finally, you're right; this really, really is ancient php.
Somthing i found pre-2004 and hacked until it worked. The
counter is missings lots of features, but I'll fix that pretty
thanks to everybody ,
