system ("pause") // causes program to pause before a return to keep interactive text on the display screen.

vegaseat,
Thanks for your datapoint! It sheds much light on the subject to an old :D 'dos' user. Also, can you tell me where this data is documented?
Thanks again, and have a great and safe holiday season.
