I'm assuming you're still referring to this code from your original email
(in config.php):

    SDV($CompSName, 0);
    Markup('CompSName','<{$var}','/\\(:CompSName: (\\w+) :\\)/e','CSName("$1")');
    function CSName ($val) {
       global $CompSName;
       $CompSName = $val;
       echo " #A- ".$CompSName;                 //output = RMS
    echo " #B-".$CompSName;                     //output = 0

Note that Markup() doesn't call CSName itself directly, it registers 
CSName as a possible function to be called later when MarkupToHTML()
is invoked on the page text.   Thus if the second echo line is actually
in the config.php, it's displaying the value of $CompSName during
PmWiki initialization, which is well before the page markup is processed
or CSName() gets invoked.
