[amibroker] Set Long, Short, Long and Short with AFL in Backtest?

[ChrisB <kris45mar@xxxxxxxxxxxx>]

I am currently trawling through the Yahoo groups, but cannot find this.

Is there AFL code that allows me to select Long only, Short only or both 
Long and Short in the Backtester, perhaps via Param or ParamList, 
instead of going into the Settings?

Regards

ChrisB
