Indralogix (CoDeSys) ANY data type

I'm using IndraWorks LOGIC 11V04.0022, trying to write a multiple move FB in ST. The editor is CoDeSys based, 3.x if I'm not mistaken.

FUNCTION_BLOCK Move3
VAR_INPUT
In1 : ANY;
In2 : ANY;
In3 : ANY;
END_VAR

VAR_OUTPUT
Out1 : ANY;
Out2 : ANY;
Out3 : ANY;
END_VAR

VAR
END_VAR

Out1 := In1;
Out2 := In2;
Out3 := In3;

I can type in the above or use the Auto declare function to create the ANY variables (it's one of the available selections). When I build it tells me I haven't declared Out1-3 and In1-3. Likewise the function block shows no I/O pins. The ANY datatype is not mentioned anywhere in the help files - so why is it selectable and highlighted as a key word in ST? If it isn't for usage similar to above then what is it for?
Thanks!

It is used when you do not know what type it will be in the future but you can not use it in real programming.
there are more words you can use here.
it has to do with type of variable so the syntax is not limiting you in typing.

Replace ANY with bool or word or time or int etc. etc
you are declaring your workable variables.

I looked in the help for Codesys 3.4 and it states that it is not implemented yet.
