01 Program entry

A standalone .norm file starts at its top-level main() function.

main() {
  printLine("Hello, Norm")
}

Output:

Hello, Norm

The braces contain the work performed when the program starts. printLine writes one line to standard output. main() has no declared result type here, so it is a Void entry point. The whole program needs only this one source file.

Save the code above as hello.norm, then run norm hello.norm in that directory with a released CLI.

Try it: Replace the greeting text with your name, save the file, and run it again.

Precise rules: Language Reference.

Next: Explicit types and assignment.
