Understanding Simantics Primitives

The following is copied from an unfinished Simantics Manual included in Script Station downloads:

"Like every computer languages, every subroutine uses a basic instruction set in the end. These instructions are called Primitives in SimAntics, and they serve a similar function as the instruction set of the Pentium. There is a primitive for calculating things, a primitive to update the object's graphic, a primitive to create an object, a primitive to move or destroy an object, and so on. The global-scope subroutines are merely tools which make it easier to access the primitives.

The ID numbers of primitives are from 0 to 100 (in decimal, that's 0 to 256). They are not stored in any IFF file, but in the main executable of The Sims, just like the instruction set of the Pentium being stored in the processor while the programs and the Windows subroutines are stored in the memory or harddisk."

I usually refer to Primitives as "functions" because this is how IffPencil refers to them.Unfortunately this does create a bit of confusion when I need to refer to the functions on the "Functional Tree" but for the most part it has not created much of a problem.
