Thanks for the input. I just wrote mecej4 and explained what I am planning to do. I assume you can see my posts too. I don’t think I am going to write anything that will be complicated enough to be slow. I wrote a program to simulate a distillation unit with several pieces of equipment. It had about 10 subroutines, each called many times and each call involved lots of iterative calculations. Despite how complex it was, when I hit the enter key to start the program, it ran in less than a second.
So I am NOT worried about speed for now.
Thanks,
Floyd
