All Data Are Created from Classes

This section describes H language data - created from classes.

All data are created from classes.

This is because all data structures are defined by classes and all data are structured data. For example,

# calling "integer" class to create an object with value of 1 
one = integer(1); 

#( calling "string" class to create an object with a sequence 
   of characters )#
hello = string("Hello!");

# calling "array" class to create an object with data elements
list = array("Apple", 3, "Orange", 5);
