The variable declaration can declare more than one variable in a comma-

separated list. A network variable can also optionally include a property list

declaration after the variable name (and the variable initializer, if present).

Declaration Specifiers

The ANSI C declaration specifiers are augmented in Neuron C by adding the

connection information, the message tag specifier, configuration property

specifiers, network variable specifiers, and timer type specifiers.
