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:
1. Open an application procedure and choose Debug > Compile, as shown in the following figure.
Figure 6. Debugging from the AppBuilder in Windows
After you choose Compile > Debug, the AppBuilder:
a. 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)
b. Initializes the Debugger
c. Sets a breakpoint on the first executable line of your procedure
d. Runs your procedure
The AVM instance immediately gives control to the Debugger at the initial breakpoint.
