QBasic Editor
The QBasic editor is very simple, but contains enough capability to support creating programs of any size.

The startup screens for QBasic as shown below. For more information on the menu options, click on one of the following links.

File	View	Run	Options
Edit	Search	Debug	Help

For it's time, the menu option above were considered reasonably complete. However, today's language IDE's are considerably more complex.

Options Menu
The Options menu provides the following options.

• Display - Changes various display options: foreground/background colors, scrollbar display, and spaces dividing each tab stop.
• Help Path - Location of QBasic.hlp file, although I'm not sure why is would be in a different place than the QBasic.exe file. I suspect, but don't know for sure, that this is a leftover from QuickBasic, which created multiple/optional folders for placing files. It also helps minimize clutter in the Open/Save menu options whose default are the folder where the QBasic.exe file is found.

• Syntax Checking - Turns on/off automatic (as you type) syntax checking within the QBasic editor.
