[amibroker] AFL code question

["richpach2" <richpach2@xxxxxxxxx>]

Hello AB Users,

Can someone explain please, how do I reference a selected value of the
signal bar?
For instance if signal bar is when  signal=cross( close, ema(close,9))
then, how do I store "High" of the signal bar for the future use so, I
can check if C>"Signal Bar High" occurred in the following bars?

I looked at BarSince, VarSet, ValueWhen and SelectedValue but, I am a
little confused and unsure which one should I use. 

Any help or comment will be appreciated.

Regards
Richard
