Running an application – PB Docs 2017

When the application seems to be working correctly, you are ready
to run it in regular mode. In regular mode, the application responds to
user interaction and continues to run until the user exits the
application or a runtime error occurs. You can rely on the default
runtime error reporting by PowerBuilder or write a script that specifies
your own error processing. You can also generate a diagnostic trace of
your application’s execution.

For how to analyze your application’s logic and performance, see
Tracing and Profiling
