When you install QBasic as a viewer, where you type in
C:\dos\qbasic.exe
modify this to read
C:\dos\qbasic.exe /run
You will find that when you click on a program now, QBasic will be loaded in, and then the program will start running at once. When the program finishes, it will exit back to the web browser. This is all that is required to streamline the operation.
To break out of the program at any time, officially you should press the ESC key, and it should exit back to the browser at once if /run is set.
Unofficially, you can break out with CTRL and BREAK, but you will be left within the QBasic interpreter. You can then look at the program.
If you ever want to write QBasic programs yourself, then finish them with a SYSTEM command, which operates with the /run directive to exit automatically from both the program and QBasic. The STOP and END commands do not do this.
We suggest that you modify the QBasic colour scheme to give grey text on a black background, so it is not too obtrusive. Choose Options and Display to do this.
