Real-time screening of multiple stocks possible?

[Rance Nunes <MetaStock@xxxxxxxxxxxxxxx>]

In MetaStock Professional the documentation states that (paraphrasing)
	The Explorer’s performance is significantly slower on intraday data
	while collecting real-time data.

Can real-time searches be performed in MetaStock Pro?

If so what is the order of magnitude of stocks that can be screened in 
real-time?  That is, if a real-time Exploration is designed, how many 
simultaneous stocks can be screened when using tick by tick information while 
collecting real-time data?  (Say on a 1-Gigahertz Pentium III with 256 Megs of 
memory).

Any assistance is appreciated.

Thanks.
