The twinBASIC IDE

The IDE consists of several fixed panes and tool windows. The Project Explorer shows the file tree of the open project; the Editor is the main code and designer surface; the Properties pane shows and edits properties for the selected item; the Toolbox lists the controls available to drop onto a form.
The debug tool windows — Call Stack, Watches, Variables, Debug Console, Diagnostics, Outline, and Memory — open during a debug session.
The tbForm and tbReport designers open when a form or report file is selected in the Project Explorer. Third-party and community addins extend the IDE with additional commands and tool windows.
