Is there a more exhaustive listing of reserved words and functions available in TS Basic than that listed in the Help menu in the software? If so, where might I access that?

I am looking for equivalents to TradeStation's "CurrentShares" word which returns the balance of shares left in the current market being traded (this being important in scaling out/exiting trades); in addition, I am looking for an equivalent to the "SetStopLoss" function.

Assistance would be appreciated. Thanks.
