We've got a inline procdir? Or are you referring to macros?

There exists a Vector Pascal compiler. They basically extend the language 
with features to do vector operations, allowing them to do ground-breaking 
performance. The Vector Pascal extenstions are under our consideration, 
however, we need the infrastructure in the compiler first. Until then, 
take a look at Vector Pascal itself.
