"result" is the actual function result parameter.

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

"RESULT" is an alias (idem) for "result" that only gets created if
{$modeswitch result} is active.

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