Читаю сейчас Help по BlackBox 1.6 rc6, читаю раздел Guided Tour и в 5-м абзаце написано:
"The component library that comes with BlackBox contains components for user interface elements such as command buttons or check boxes; various components that provide word processing functionality (Text subsystem); various components that provide layout management functionality for graphical user interfaces (Form subsystem); database access components (Sql subsystem); communication components (Comm subsystem); and a number of development tool components such as compiler, interface browser,debugger, and so on (Dev subsystem)."
Насчет debugger-а он действительно есть или это просто небольшое преувеличение в Help-е?
