APL\360 evolved rapidly during its early development within IBM and more slowly as it became available to outside users. Here we show the primitives described in its [http://www.softwarepreservation.org/projects/apl/Manuals/APL360CONTRIBUTEDPROGRAMLIBRARY/view documentation] in 1968 when it was first released as a stand-alone product (a [[wikipedia:IBM Type-III Library|Type-III Library]]). Later additions include [[Matrix Inverse]] and [[Matrix Divide]]; [[Execute]], [[Format]], and [[Scan]] introduced by [[APL.SV]]; and an [[Function axis|axis]] and [[Laminate]] form for the [[Catenate]] function. | |||
