array question

["o_2_b_sean" <seanrmartinez@xxxx>]

Here is a bit of AFL to find the first bar in the 3 pm hour:

TimeCondition = Hour() == 15 AND (Ref(Hour(), -1) == 14);

How could I take the close of that bar and store it continuously in 
an array until timecondition was true again. It is probably easy, but 
I am not getting it.
