'''APL2''' was a significant re-implementation of APL by [[IBM]] which was developed from 1971 and first released in 1984. It provides many additions to the language, of which the most notable is nested (non-rectangular) array support. As of 2018 it is available for mainframe computers running z/OS or z/VM and workstations running AIX, Linux, Sun Solaris, and Microsoft Windows. | '''APL2''' was a significant re-implementation of APL by [[IBM]] which was developed from 1971 and first released in 1984.
