title: I Installed IntelliJ Idea with the Scala plugin. Why don't I have a scalac file anywhere?
body: <p>It is my second day with <code>Scala</code> and <code>IntelliJ Idea</code>. I can run a <code>Hello World</code> program. I want to enter Scala commands interactively, in a REPL. However, the console does not work. Supposedly there is a bug. So I tried to go to the <code>Command Prompt</code> and run <code>Scala</code> with <code>scalac.exe</code>. But no file <code>scalac.exe</code> or <code>scala.exe</code> exists on my hard disk (I checked). What should I do?</p>
