User interface > Debugging and executing > Checking success
As soon as the debugger is started, the status bar is colored yellowly. The yellow color indicates that no fault has appeared till now, but the processing isn't completed yet.
If the execution of the transformation was successful, then this is signaled by a green colored status bar in the debug mode.
If no following token is found before the text ends, the parser is stopped and the status bar is colored orangely.
Furthermore it is possible to execute single steps because semantic actions still can follow on the abortion of the recognitions.
A red status bar finally shows that the parser finished with a fault.
If the source text wasn't processed completely, the following lines are appended to the target text:
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XX XX
XX An error occurred. The transformation is incomplete! XX
XX XX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
More information about the fault is shown in the log window.
