'''SHARP APL''' was a standalone version of APL offered by [[I.P. Sharp Associates]] (IPSA), who had previously offered APL interpretation as a timesharing service. IPSA employed many notable APL designers including [[Ken Iverson]], and SHARP APL was the source of many developments in [[flat array theory]].
'''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.

== Primitive functions ==
 
The primitives shown here are those for SHARP APL around 1987, near the end of the decline of [[time-sharing]] APL. Some primitives from [[A Dictionary of APL]] were added after this, including [[Find|In]] (<syntaxhighlight lang=apl inline>⍷</syntaxhighlight>), [[Nubsieve]] (<syntaxhighlight lang=apl inline>≠</syntaxhighlight>), and [[Raze]] (<syntaxhighlight lang=apl inline>↓</syntaxhighlight>), and these appear in [[SAX]].
