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

Run Menu
The Run menu provides the following options. Keystroke shortcuts are shown in the image above.

• Start - Starts program execution, beginning with the first line of code.
• Restart - Repositions the cursor to the first line of the main program code, but does not start execution of the program.
• Continue - Continues execution of a stopped program at the point in which the program was previously stopped.

Ctrl-Break
Execution of a program can be stopped using the Ctrl-Break key combination. When used, the Output window is replaced with the Program window, where the next line to execute is highlighted.
