Online Manual: Program Startup

(Note to Readers: This is perhaps the least stable section of this document. Since our research project also includes a module system which is under development, the proposal in this section is only for the practical use of Classages and might be changed over time.)

A Classages program is composed of classages, with one of them being the startup classage, similar to Java's class with main method defined. Followed is the most simple Classages program: 

startup classage MyApp {
   main(String[] args) {
     create X();
   }
}

classage X {
  X() {
    int x = 0;
  }
}
The startup classage is decorated with the keyword startup, and has a special method main defined: it takes in a String array as arguments (command line input), and does not declare a return type.

The classages forming one application can straddle in in multiple physical files. The compiler does not allow for any two classages having the same name during compilation.
