Roger,

What on this planet Earth are you doing?

Take a look at this Wikipedia Web page on Brownian Motion because that is just what it appears you are doing.

I am not trying to get you to invent a new computer programming language. You indicated that you were thinking of moving from TrueBasic to Fortran. And you checked several Fortran compilers and determined that one appears to be the best performer.

All I am suggesting is that if you want to work with Fortran then it would probably be a good idea to check on the various libraries and determine what might be the best way to work with a Fortran compiler that will let people do things such as draw charts. Fortran normally just does calculations from what I understand. But it is a very mature language and can link with libraries that will probably let it do just about anything.

The situation that we have is that it sounds like Skywise is moving from X=Basic to C. I am giving up on Perl and am looking for a replacement language. And I can’t determine what on this planet Earth you are doing!

It would be helpful to have at least two living people who are using the same computer language to develop scientific programs. If you want to use Fortran then fine. If Julia looks more attractive then that might be even better though I am not yet sure if it is a “mature” language as Fortran is. But, TrueBasic is a dead end in my opinion. It is apparently much slower than Fortran for calculations etc. and is largely incompatible with Windows.

That SunGP program should be translated into some language that people can work with. And Fortran looks okay to me. But there has to actually be some type of decision made regarding a programming language that people will stick with for at least a week.
