The call chain is: - you run flowcpp and feed it with .flow file; - flowcpp see that it is source file and calls compiler - compiler produces .bytecode file

The call chain is: - you run flowcpp and feed it with .flow file; - flowcpp see that it is source file and calls compiler - compiler produces .bytecode file - flowcpp executes .bytecode file and runs file you called. You can call compiler directly with flowc or flowc1 commands.
