By picking the wild card matching expression for “trace” you can select which files that tracing will be switched on for.
For a large application this is essential for being able to make sense of it.
Try these different command line invocations of the sandbox:
./test --trace "main" ./test --trace "*" ./test --trace "APP*"
If your application doesn’t make use of the BASargParser class then you can call the function BAStrace directly, i.e.:
BAStrace("BAS*"); // trace all files starting with BAS.
