Hi Rocky

Or for this simple task, at zero cost, FreeBASIC:

It comes from http://www.powerbasic.com 
It is commercial software.   However they have a great deal on at the moment
on the 
previous version..

The current version 9 sells for $199.

Version 8 is  available as "Classic Powerbasic".  It normally sells for $99
but is currently on special for $49.

It probably could be done in VS - but not nearly as easily.
