[amibroker] Backtest with separate params for each symbol

[Martin Simek]

I am trying to write system with separate params values for each symbol.
For example:

if (Name() == "AAPL" )
{ param1 = 10; param2 = 20; }
else if(Name() == "MSFT")
{ param1 = 30; param2 = 40; }

This example doesn't work because if statement needs only number 
expressions.
Any idea how to get separate params values for each symbol?
Thanks

Martin
