The Help feature is the best that I have ever seen! The "Help" in most programs is often a waste of time as my questions are not normally addressed in Help. However, yours is perfect! I needed to do an ARCSIN() function and your program Help instantly showed me the trig identity required!
As an Electrical Engineer, I am very particular about design details. I sense the same spirit in your company as your product rocks! It's good to know that there are companies out there that truly want to make things right! I will surely recommend PowerBASIC.
