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. | {{Infobox array language | ||

APL2's extensions to [[ISO 8485:1989]] were standardised as [[ISO-IEC-13751]]. No further core language features have been added, | APL2's extensions to [[ISO 8485:1989]] were standardised as [[ISO-IEC-13751]]. APL2 supports entry of [[complex number]]s in the following forms: | ||
# Real and imaginary part separated by the letter <source lang=apl inline>J</source> and no spaces, e.g. <source lang=apl inline>0J1</source> | |||
# Magnitude and angle in degrees separated by the letter <source lang=apl inline>D</source> and no spaces, e.g. <source lang=apl inline>1D90</source> | |||
# Magnitude and angle in radians separated by the letter <source lang=apl inline>R</source> and no spaces, e.g. <source lang=apl inline>1R1.5708</source> | |||
No further core language features have been added, with improvements instead consisting of powerful [[Quad name]]s. | |||
