[amibroker] How to filter during scan?

["Pete" <dryheat3@xxxxxxx>]

Can someone please explain to me how to select criteria for my scans?
The Filter keyword is only working during Explore. It took me over an
hour of screaming at the computer to figure out 'Filter' just wasn't
programed to work in scan mode.
Example:
Buy = Close > 60;
Filter = LastValue(Close) > 70 ;
AddColumn( Close, "Close", 1.3 ) ;
AddColumn( MA(Close, 45), "MA 45" ) ;

Pressing the Explore button omits all stock less then 70. Pressing the
Scan button includes all stocks greater then 60. Someone might think
about changing that...

So, here's what I've come up with so far:
Cond1 = UTrnd > DTrnd AND Cross(sht,lng) ;
Cond2 = DTrnd > UTrnd AND Cross(lng,sht) ;
fltr = Close > 50;
Buy = Cond1 AND fltr;
Sell = Cond2 AND fltr;
Cover = Cond1 AND fltr;
Short = Cond2 AND fltr;

This is the only way I've been able to restrict the results of my scans
to stocks greater then 50. I have to add the clause "AND Close > 50;" at
the end of every buy, sell, cover, and short statement. Is there any
other way to accomplish this? Just looking for a sanity check.
