Hello Matthew,
It was originally my plan to met my Apple spreadsheets(I am an amateur on programming) turned into an Apple Program, but all the experts I contacted said that it would be difficult to do.
I was told that a data base type program would be needed. In the end I had Chris Kruidenier write the VORTEX program for DOS and then for Windows...but it is still in a form that needs some modifying I think. I am not going to develop an Apple version but I was interested in doing so lately. Dutch AIMer Rien is working on this idea. When he is ready for it you will hear about it. He can be contacted on this Board.
Regards,
Conrad
