System.BreakOnError (gb)

Static Property BreakOnError As Boolean

Return or set if a debugged program must break if an error occurs, even if there is a error management catching the error.

That property allows to enable or disable the "break on error" IDE feature at runtime.

Unless you write your own debugger for Gambas programs, this property is likely not useful to you. Setting this property to True is as if you deleted the Try, Catch and Finally keywords from the language.
