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.
