'''SHARP APL''' was an APL implementation offered by [[I.P. Sharp Associates]] (IPSA), originally as part of its [[time-sharing]] service and later as a stand-alone product. It was split off from [[STSC]]'s [[APL*PLUS]], which until then had been sold jointly by the two companies. SHARP APL was the source of many developments in [[flat array theory]], driven by [[Ken Iverson]] and other APL designers at IPSA. | '''SHARP APL''' was an APL implementation offered by [[I.P.
