Right away, in initials (4)

I believe the answer is:

asap

(Other definitions for asap that I've seen before include "At one's earliest convenience" , "Notation or acronym meaning without avoidable delay" , "As soon as possible (abbrev.)" , "Notation meaning without delay, treat as urgent" , "Initials notation meaning with all possible speed" .)

I've seen this clue in The Wall Street Journal.
