Add the explicit if-then-elseif-else syntax to the list of command allowable in the statements and function definitions.

Hi,

Exactly as in the subject.

There is a need to add the explicit, text-based, if-then-elseif-else syntax to the list of command allowable in the statements and function definitions.

I know I can use C++ style of the if-then-else-elseif syntax, but in more nested expresions the readibility of it gets worse and worse very quickly.

Having this functionality would simplyfy the readibility of the statements.

Add the select-case to the list.
