Line 361: There is one type of box, two types of literals (8 bit wide and 16 bit wide), and a variety of types of numerics. Sparse arrays are also (partially) supported and treated internally as a distinct ~~datatype~~datatypes, implemented under the covers as a ~~pair~~sequence of arrays (one to indicate which indices have values, and another to hold the corresponding values, and also a default value to fill in the rest). The primary implicit type conversion in J applies to numeric values.
