A word starting with a lower-case letter (such as OK) represents a constant, it is called atom, including the constant name, function name, and module name.
Erlang Comments start with %. Erlang uses the underscore "_" to represent any variable, similar to the defaul

In addition, if the program is run in the Delphi ide window, it will not be run once, because there is already a window with the same class name and title: The Window port at design time.

The Atom protocol allows providers of network resources, such as news, community sites, and blogs, to chain their content through the Web. In a typical Atom application, content providers typically chain a file or a web feed and make it available on the web.

1. The variable "single assignment" in Erlang means that the variable can only be assigned one time.2. Variables must begin with a "capital letter".
Two: Atoms
An atom is equivalent to an enumeration type in C + +, but the value of an atom in Erlang is itself.
Atoms are a string that starts with "lowercase letters," but if you use single quotes, the name of the
