To be honest this has annoyed me a few times. This behavior is there for many releases, before I actually started working on the debugger. So I agree to change it ... Maybe when debugging, we could display what the user is expecting, i.e the system information we have when we do not debug, and append the execution information. So for instance: System name: ec target: bench configuration: C:\_dev\trunk\Src\Eiffel\Ace\ec.ecf location: c:\_dev\compile compilation: c:\_dev\compile\EIFGENs\bench tag_concurrency: tag_concurrency_thread console: yes Root Class EB_KERNEL (interface): make Launching system : - profile = `profile #1' - directory = `C:\_dev\trunk\Src\Eiffel\Ace' - arguments = `-gui' And renaming "Launching system : " by "Execution" Would it make sense?
