Comments

If you don't want to program, you can leave QBASIC alone. However, if you wish to use EDIT or DOS 6's HELP program you must have all the QBASIC files available as these are used by EDIT and HELP.

QBASIC is a good environment in which to learn BASIC. It's more or less standard now, especially as Visual BASIC can understand most QBASIC commands. Most of the more powerful functions available in QuickBASIC have been removed so it's impossible to call DOS interrupts, for example.
