atoms are ncif(name char int float) and mdhrst(month day hour min sec milli)
|
|
vector is unitype list of atoms, e.g. (2;3) is 2 3 and ("a";"b") is "ab"
|
|
matrix is uniform list of vectors, e.g. m:(0 1 2;1 2 3)
|
|
atomic functions (+-*%!&|<>=$;-%~_^$) penetrate, e.g. 2 3+m is (2 3 4;4 5 6)
|
|
default function parameters are x y z, e.g. {z+x*y}[3;2;1] is 7
|
|
indexing and function call use []'s, e.g. m[1;2] is {x+y}[1;2] is 3
|
|
no precedence among verbs: 2*4-3 is 2* 4- 3 is 2
|
|
grammar: E:E;e|e e:nve|te| t:n|v v:tA|V n:t[E]|(E)|{E}|N
|
|
unary list needs ",", e.g. 2(atom) ,2(list)
|
|
unary verb arg needs ":", e.g. #'(take each) #:'(count each)
|
|
unary call doesn't need []'s, e.g. f x is f[x]
