Scala programs can accept run-time variables as command line arguments. Here is an example of how to access the variables.
object CmdArgs {
def main(args: Array[String]) {
println("All Command Line Arguments: " + args.toList)
println("First argument: " + args(0)) // First argument
}
}Compile it, and run it with some command line arguments. If you don't provide at least one argument it will fail due to out of bounds index.
