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's extensions to ISO 8485:1989 were standardised as ISO-IEC-13751. APL2 supports entry of complex numbers in the following forms:

  1. Real and imaginary part separated by the letter J and no spaces, e.g. 0J1
  2. Magnitude and angle in degrees separated by the letter D and no spaces, e.g. 1D90
  3. Magnitude and angle in radians separated by the letter R and no spaces, e.g. 1R1.5708

No further core language features have been added, with improvements instead consisting of powerful Quad names.

The entire APL2 Products and Services Team was awarded the Iverson Award in 2007.
