NARS2000 is an open-source APL interpreter written by Bob Smith, a prominent APL developer and implementer from STSC in the 1970s and 1980s. NARS2000 contains advanced features and new datatypes and runs natively on Microsoft Windows, and other platforms under Wine. It is the spiritual successor of the first NARS (Nested Arrays Research System) which was designed and implemented in the early 1980s as a testbed for new ideas in APL, principally with nested arrays.

Language ideas include new functions, operators, datatypes, and many other extensiosn. The project is free open source software.

Primitives

The following list is incomplete.

Functions

Glyph Monadic Dyadic
Indices Array Lookup (high-rank Index-Of)
< Condense Less Than
> Dilate Greater Than
\ Expand

Index Generator Index Of
Matrix Inverse Matrix Divide
Tally Mismatch
Partitioned Enclose
π Factors Primes
Shape Reshape
Square Root Root

§ Symmetric Difference

Operators

One feature of NARS2000 is its heavy use of experimental primitive operators. In the table below, operators which are unknown or obscure in the APL world are linked to the NARS2000 wiki rather than the APL wiki.

Glyph Valence Monadic call Dyadic call
Dyadic Power
Monadic Commute
Dyadic Composition (Over)
Dyadic Compose
Dyadic Rank
Monadic Combinatorial
Dyadic Convolution
. Dyadic Inner Product Determinant
Monadic Numerical Derivative
Monadic Matrix
Monadic Multisets
Monadic Null
a∘/ Special Mask
a∘⌿ Special Mask First
a∘\ Special Mesh
