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
⍷ Find
⍳ Index Generator Index Of
⌹ Matrix Inverse Matrix Divide
≢ Tally Mismatch
⊂ Partitioned Enclose
π Factors Primes
⍴ Shape Reshape
√ Square Root Root
.. Sequence
⊆ Subset
⊇ Superset
§ Symmetric Difference
~ Not Without

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
a∘⍀ Special Mesh First
⍠ Dyadic Variant
