APL's core syntactic principles are:
- Arrays as first class citizens
- Functions take arrays as input and produce arrays as output
- Operators take functions as operands and produce derived functions
Example array definitions
simplenumvec←1 2 3 4 ⍝ A simple numeric vector
simplecharvec←'ABCD' ⍝ A simple character vector
Example function definition
∇ r←l Tradfn r
[1] ⍝ An infix (dyadic) tradfn
[2] r←l r
∇
Example operator definition
∇ r←larg(Main OVER PreProc)rarg
[1] r←(PreProc larg)Main(PreProc rarg)
