ok . i need to write a simple expression but I am Stuck.  
 the goal is :   
 when object A is selected select object B.  
 well I was thinking that I can do it with an if statment  
 aka:  
$s = `ls -sl`;  
if ( $s == A)  
 select -tgl B:

well thats the Idea . of course it does not work . so Could you help me to write the expression that will .

If you need a script that continually monitors the selection state of an object you need to look into the scriptJob command.

thanks Man .  
 actually I ended up using the For Function to get what I want:

$q = `ls -sl` ;  
// print $q;  
for ( $x in $q ) {  
 if ( $x == "ball" )  
 select -add ball1;  
}

anyway thnks for the input.
