Starting the Debugger from the AppBuilder runs the Debugger in application mode, ready to debug the procedure that is running and any other procedures you choose.

To start a debugging session from the AppBuilder:

Open an application procedure and choose Debug > Compile, as shown in the following figure.
Figure 1. Debugging from the AppBuilder in Windows


After you choose Compile > Debug, the AppBuilder:

  1. Saves a temporary file containing your procedure to the current working directory, using a unique, alphanumeric filename with a .ab extension (as the AppBuilder always does)
  2. Initializes the Debugger
  3. Sets a breakpoint on the first executable line of your procedure
  4. Runs your procedure

The AVM instance immediately gives control to the Debugger at the initial breakpoint.
