HOW TO reference a function name with variables?

[kent@koylia.org]

Morning and back to this topic on a philosophical basis. As I have said, I AM NOT a programmer!!! -but having the ability to 'reference a function name via variables' seems like something that would be very powerful and of great use, that is when you create an 'exe'.

MY QUESTION =

Is this something that in fact would be technically very difficult to implement when creating 'exe's's?

OR

Is it just not that needed by QM users?

Just curious? & Thanks!
