[amibroker] How to control behaviour of Paramstr() ?

["wecus" <member@xxxxxxxx>]

For relative comparison of two stocks I use this code to set up a 
default:

if (GroupID() == 6 OR GroupID() == 7 ) 
    CompareTickerDefault = "^GDAXI";
else
    CompareTickerDefault = "^IXIC";

then I set the variable to be processed later using paramstr():

CompareTicker = ParamStr( "Compare "+Name()+" 
with:",CompareTickerDefault);

This way an individual variable get's initialized for each stock (as 
can be watched by pressing CTRL-R) as I cycle through my database. To 
get around this I tried dropping the 'name()': 

CompareTicker = ParamStr( "Compare with:",CompareTickerDefault);

Unfortunately this doesn't refresh as it should, it looks like 
CompareTicker is evaluated only once and then cached from there on. 
Is there a way to tell AB to flush the cache or delete the variable 
every time I select a new stock?

TIA
Andreas
