"result" is the actual function result parameter.

"FUNCTIONNAME" is an alias (internally an "absolute" variable") for

"RESULT" is an alias (idem) for "result" that only gets created if

Lowercase variables cannot be accessed directly by Pascal code, and only
by the compiler itself (or through absolute aliases).
