I think I realize what is your problem: PHP does not warn if you miss a 
parameter. C++ does unless you specify a default value for the 
parameter. But this is nothing that should stop us to use customizable 
functions (by extra parameters). Global variables just as confusing.

We will see. :-)

No, as index.php starts with <? include "applib.php" ?> which clearly 
says that some functions and variables might be declared there. If 
releases.inc.php starts with an <? include "applib.php" ?> I don't have 
(such a big) problem with $_appFormal. But now there is an assumption 
that releases.inc.php is included only in a file where applib.php is 
already included and I really don't like this.
